How to post multiple inputs in database - forms

I'm working with Codeigniter, on a sales targets' form for salesmen.
They have to input values for each product, locality, year, etc.
Product and locality are already get with existing database: no need to set rules (see controller).
When I checked the post (with enable_profiler of Codeigniter), I get this:
The problem is these datas don't insert into the database table.
I read and tested a lot, but always blocked.
Here is my model:
public function add($params)
{
$this->db->insert($this->table, $params);
return $this->db->insert_id();
}
My controller:
$this->load->library('form_validation');
$this->form_validation->set_rules('year', 'Year', 'required|integer');
$this->form_validation->set_rules('prevision', 'Prevision', 'required');
$this->form_validation->set_rules('value', 'Value', 'required|integer');
if ($this->form_validation->run()) {
$params = array(
'year' => $this->input->post('year'),
'prevision' => $this->input->post('prevision'),
'locality_id' => $this->input->post('locality'),
'product' => $this->input->post('product'),
'value' => $this->input->post('value'),
);
$this->Objectif_model->add($params);
redirect('admin/objectif');
} else {
$this->layout('admin/objectif/add');
}
And my view with inputs:
<?php foreach ($products as $product) : ?>
<tr class="form-group">
<td class="bg-warning">
<?= $product->grp_product; ?>
</td>
<td class="bg-warning product">
<?= $product->code; ?>
</td>
<?php foreach ($localities as $locality ) : ?>
<td>
<input type="text" class="form-control valeur" placeholder="Value k€" name="value[]" data-validation="number" data-validation-ignore="./" data-validation-optional="true" />
<input type="text" name="year[]" />
<input type="text" name="prevision[]" />
<input type="text" name="product[]" value="<?= $product->code ?>" />
<input type="text" name="localite_id[]" value="<?= $locality->id ?>" />
</td>
<?php endforeach; ?>
</tr>
<?php endforeach; ?>
Hope you will help me.

I find my answer.
In my controller, I had to pass each post in a variable and made a loop.
//action post in a var for each data
$id = $this->input->post('id');
$prev = $this->input->post('prevision');
$year= $this->input->post('year');
$locality_id = $this->input->post('locality_id');
$product = $this->input->post('product');
$value= $this->input->post('value');
if ($this->form_validation->run()) {
$count_id = count($id);
if (isset($id)) {
for ($i = 0; $i < $count_id; $i++) {
$obj[$i] = array(
'id' => $id[$i],
'prevision' => $prev,
'year' => $year,
'locality_id' => $locality_id[$i],
'product' => $product[$i],
'value' => $value[$i]*1000
);
} // endfor
if (isset($obj)) {
$this->Objectif_model->add_obj($obj);
} // endif
}// endif isset
}// endif form validation

Dynamic form input fields in Cakephp 3

I have seen this: https://waltherlalk.com/blog/dynamic-form-input-fields and have been active in this: Dynamically add form field rows - cakePHP. I have reached the stage where the setup is as per the original tutorial with changes made as per the Stackoverflow post from monsur.hoq.
The form is working fine but, upon saving, it only saves the 'student' part of the data: nothing is sent to grades. The add part of my controller currently looks like this:
public function add()
{
$student = $this->Students->newEntity();
if ($this->request->is('post')) {
$student = $this->Students->patchEntity($student, $this->request->data);
if ($this->Students->save($student)) {
$this->Flash->success(__('The student has been saved.'));
return $this->redirect(['action' => 'index']);
} else {
$this->Flash->error(__('The student could not be saved. Please, try again.'));
}
}
$this->set(compact('student'));
$this->set('_serialize', ['student']);
}
All code is as per bake or the tutorial shaped by the monsur.hoq post.
If anyone could help me to arrive at a working Cakephp3 example of the Walther Lalk tutorial I'd be very grateful.
The debugging toolbar shows the following SQL being produced on submitting the form:
INSERT INTO students (name, created, modified)
VALUES
(
'Test Two', '2016-09-13 16:04:07',
'2016-09-13 16:04:07'
)
All that serves to do is confirm the problem. Debugging in PHP Storm on form submission reveals the following:
$_POST = {array} [3]
_method = "POST"
name = "Test Four"
Grade = {array} [1]
0 = {array} [3]
id = ""
subject = "Maths"
grade = "3"
The add.ctp is as follows:
<nav class="large-3 medium-4 columns" id="actions-sidebar">
<ul class="side-nav">
<li class="heading"><?= __('Actions') ?></li>
<li><?= $this->Html->link(__('List Students'), ['action' => 'index']) ?></li>
<li><?= $this->Html->link(__('List Grades'), ['controller' => 'Grades', 'action' => 'index']) ?></li>
<li><?= $this->Html->link(__('New Grade'), ['controller' => 'Grades', 'action' => 'add']) ?></li>
</ul>
</nav>
<div class="students form large-9 medium-8 columns content">
<?= $this->Form->create($student) ?>
<fieldset>
<legend><?= __('Add Student') ?></legend>
<?php
echo $this->Form->input('name');
?>
</fieldset>
<fieldset>
<legend><?php echo __('Grades');?></legend>
<table id="grade-table">
<thead>
<tr>
<th>Subject</th>
<th>Grade achieved</th>
<th> </th>
</tr>
</thead>
<tbody></tbody>
<tfoot>
<tr>
<td colspan="2"></td>
<td class="actions">
Add grade
</td>
</tr>
</tfoot>
</table>
</fieldset>
<script id="grade-template" type="text/x-underscore-template">
<?php echo $this->element('grades');?>
</script>
<?= $this->Form->button(__('Submit')) ?>
<?= $this->Form->end() ?>
</div>
<script>
$(document).ready(function() {
//I changed undescore default template settings
_.templateSettings = {
interpolate: /\{\{(.+?)\}\}/g
}
var
gradeTable = $('#grade-table'),
gradeBody = gradeTable.find('tbody'),
gradeTemplate = _.template($('#grade-template').remove().text()),
numberRows = gradeTable.find('tbody > tr').length;
gradeTable
.on('click', 'a.add', function(e) {
e.preventDefault();
$(gradeTemplate({key: numberRows++}))
.hide()
.appendTo(gradeBody)
.fadeIn('fast');
})
.on('click', 'a.remove', function(e) {
e.preventDefault();
$(this)
.closest('tr')
.fadeOut('fast', function() {
$(this).remove();
});
});
if (numberRows === 0) {
gradeTable.find('a.add').click();
}
});
</script>
Change from CakePHP 2 to CakePHP 3 fields name conventions,
Grade.{$key}.grade to grades.{$key}.grade
Create View/Elements/grades.ctp file with the following contents.
https://waltherlalk.com/blog/dynamic-form-input-fields
<?php
$key = isset($key) ? $key : '<%= key %>';
?>
<tr>
<td>
<?= $this->Form->hidden('grades.{$key}.id') ?>
<?= $this->Form->text('grades.{$key}.subject'); ?>
</td>
<td>
<?= $this->Form->select("grades.{$key}.grade",
[
'A+',
'A',
'B+',
'B',
'C+',
'C',
'D',
'E',
'F'
],
[
'empty' => '-- Select grade --'
]); ?>
</td>
<td class="actions">
Remove grade

Codeigniter validate form is not working

I have the same implementation for my login for and is working, but on my contact form it is not, and I have no error message just re routed to the home page.
the weird thing is if in my controller i implement the index function like this:
public function index() {
$this->myprocess();
}
and my view using
<?php
$attributes = array('class' => 'form-contact', 'id' => 'myform2');
echo form_open('contact',$attributes);
?>
instead of calling my function myprocess all the validations work but no use for a form with out my header footers etc.
bellow that is how i want my code to work i hope yall can help me.
my controller:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class contact extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->model('contact_m');
}
public function index()
{
$data = array('title' => 'Contact', 'main_content' => 'contact_v');
$this->load->view('template', $data);
}
public function myprocess(){
$this->form_validation->set_rules('dfname', 'Name', 'required|trim|xss_clean|max_length[40]');
$this->form_validation->set_rules('dfemail', 'Email', 'required|trim|xss_clean|valid_email|max_length[50]|callback__verifyemail');
$this->form_validation->set_rules('dfmsg', 'dfmsg', 'trim|xss_clean');
$this->form_validation->set_error_delimiters('<br /><span class="error">', '</span>');
if ($this->form_validation->run() == FALSE) // validation hasn't been passed
{
$this->load->view('contact_v');
}
else
{
$form_data = array(
'dfname' => set_value('dfname'),
'dfemail' => set_value('dfemail'),
'dfmsg' => set_value('dfmsg')
);
if ($this->contact_m->SaveForm($form_data) == TRUE)
{
redirect('contact/success');
}
else
{
echo 'An error occurred saving your information. Please try again later';
}
}
}
function success()
{
echo 'this form has been successfully submitted with all validation being passed. All messages or logic here. Please note
sessions have not been used and would need to be added in to suit your app';
}
public function verifyemail(){
$name = $this->input->post('dfName');
$pass = $this->input->post('dfemail');
if($this->contact_m->email_exist($name,$pass)){
if ($this->session->userdata('site_lang') == 'portuguese')
{
$this->form_validation->set_message('_verifyuser','Usuario Inexistente!');
}else{
$this->form_validation->set_message('_verifyuser','User Not Found!');
}
$this->index();
return false;
}else{
return true;
}
}
}
?>
my view:
<div class="container">
<div class="row">
<div class=" col-md-4 col-md-offset-4">
<?php echo br(2)?>
<div class="account-wall drop-shadow">
<?php
$title = $this->my_library->my_title($this->session->userdata('site_lang'),FORM_CONTACT);
echo '<h1 class="text-center login-title">'. $title. '</h1>';
echo br(1)
?>
<?php
$attributes = array('class' => 'form-contact', 'id' => 'myform2');
echo form_open('contact/myprocess',$attributes);
?>
<p>
<label for="dfname">Name</span></label>
<?php echo form_error('dfname'); ?>
<input id="dfname" type="text" class="form-control" placeholder="Name" name="dfname" maxlength="40" value="<?php echo set_value('dfname'); ?>" autofocus />
<?php echo br(1)?>
</p>
<p>
<label for="dfemail">Email</span></label>
<?php echo form_error('dfemail'); ?>
<input id="dfemail" type="text" class="form-control" placeholder="Email" name="dfemail" maxlength="50" value="<?php echo set_value('dfemail'); ?>" />
<?php echo br(1)?>
</p>
<p>
<label for="dfmsg">Message</label>
<?php echo form_error('dfmsg'); ?>
<?php echo form_textarea( array( 'name' => 'dfmsg', 'rows' => '4', 'cols' => '43', 'value' => set_value('dfmsg') ) )?>
<?php echo br(1)?>
</p>
<p>
<?php echo form_submit( 'submit', 'Submit'); ?>
</p>
<?php form_close();?>
</div>
</div>
</div>
</div>
<?php echo br(5)?>
your callback function for validation need an underscore for prefix name :
public function _verifyemail()
and you need to call the process function :
public function index()
{
$data = array('title' => 'Contact', 'main_content' => 'contact_v');
if($this->input->post())
$this->myprocess();
$this->load->view('template', $data);
}
So after all this days and examining all my code and re-writing all of it i found the problem.
for some reason this line wasnt working : echo form_close(); so my first form was aways open messing up asll my validation after writing on all of then it starting working.

Input Form Using Codeigniter and Bootstrap 3

I'm using Codeigniter, styled with Bootstrap 3 to build a website.
I can't stylize the text-fields built by the PHP/Form Helper, as I'm not sure where to use the tags, every solution I've tried has resulted in either an extra text field, or just the addon appearing, or nothing at all.

Codeigniter - update table from form with checkbox

I'm trying to update a MySQL table with Codeigniter.
My model code is:
function update_customer_records($updatedrow)
{
$this->db->where('id',$this->input->post('id'));
$this->db->update('customers',$updatedrow);
}
My view is:
$attributes=array(
'name'=>'updatecustomer',
'id'=>'updatecustomer',
);
echo form_open('masterdata/manage_customers',$attributes);
?>
<table>
<tr>
<td> </td><td> </td><td>Customer Name</td><td>postalcode</td>
<tr>
<?php if(isset($records)) : foreach ($records as $row) : ?>
<tr>
<td>
<?php echo anchor('masterdata/customers_updated/'.$row->id, img(array('src'=>'images/delete_icon.png','border'=>'0','alt'=>'Delete'))); ?>
</td>
<td>
<input type=checkbox name="editcustomer[]" id="editcustomer[]" value="<?php echo $row->id ?>">
</td>
<td>
<input type="text" name="customername_<?php echo $row->id ?>" id="customername_<?php echo $row->id ?>" value="<?php echo $row->customer_name ; ?>" >
</td>
<td>
<input type="text" name="customername_<?php echo $row->id ?>" id="customername_<?php echo $row->id ?>" value="<?php echo $row->postalcode ; ?>" >
</td>
</tr>
<?php endforeach ; ?>
</table>
<input type="submit" value="Update Selected">
<?php else : ?>
<h2> No Records Found</h2>
<?php endif; ?>
<?php echo form_close(); ?>
My controller is :
function manage_customers()
{
$data['title']="Manage Customers";
//query model to get data results for form
$data=array();
if($query=$this->model_master_data->get_records()){
$data['records']=$query;
$this->load->view("master_data/view_master_data_header",$data);
$this->load->view("master_data/view_master_data_nav");
$this->load->view("master_data/view_content_master_data_manage_customers",$data);
$this->load->view("master_data/view_master_data_footer");
$editcustomer = $this->input->post('editcustomer');
if(isset($editcustomer)){
//begin outputting id of selected checkbox
foreach ($editcustomer as $row) :
echo $row;
$updatedrow=array(
'id'=>$row,
'postalcode'=>'44444'
);
$this->model_master_data->update_customer_records($updatedrow);
endforeach;
}
I have two issues :
How do I stop the foreach from running if a checkbox has not been checked.
How do I pass the array to the model correctly so that the update runs?
Thanks in advance as always.
First of all I found two fields in the form with the same name and id (given below) and in one field you are setting it's value customer_name and in another you are setting postalcode.
<td>
<input type="text" name="customername_<?php echo $row->id ?>" id="customername_<?php echo $row->id ?>" value="<?php echo $row->customer_name ; ?>" >
--^^--
</td>
<td>
<input type="text" name="customername_<?php echo $row->id ?>" id="customername_<?php echo $row->id ?>" value="<?php echo $row->postalcode ; ?>" >
--^^--
</td>
So I think (probably) the name and id of the second field should be postalcode according to it's value.
Also you don't need to worry about foreach loop because the code inside the loop ll run only if there are checked check boxes on the form because unchecked check boxes won't be submitted but you can check and run the loop using following code
if( $this->input->post('editcustomer') != false )
{
foreach ($editcustomer as $row)
{
// code here
}
}
The if condition will return false if the editcustomer is not found or not submitted with the form. Also there is no id field in your form and in this case you can't use $this->input->post('id'), so if you need to check the check box id in the where clause of your model then you can use
In The controller :
if( $this->input->post('editcustomer') != false )
{
$this->load->model('model_master_data');
foreach ($editcustomer as $row_id)
{
$data = array( 'postalcode' => '44444' );
$this->model_master_data->update_customer_records( $row_id, $data );
}
}
I don't think you need to pass 'id'=>$row, because you probably don't wan't to update this field. Also you should use form validation to check the form input before updating the record (you may set the postcode field required to bound the user to enter a postcode).
In The Model :
function update_customer_records( $id, $data )
{
$this->db->where( 'id', $id );
$this->db->update( 'customers', $data );
}
So it'll do something like this (pseudo code)
update the customers table set `postalcode` = '44444' where `id` = $id
Update :
I think you can also use the update_batch.
In The controller :
if( $this->input->post('editcustomer') != false )
{
$data = array();
foreach ($editcustomer as $row_id)
{
$data[] = array( 'id' => $row_id, 'postalcode' => '44444';
}
$this->load->model('model_master_data');
$this->model_master_data->update_customer_records( $data );
}
In The Model :
function update_customer_records( $data )
{
$this->db->update_batch('customers', $data, 'id');
}
Duplicate topic with "Codeigniter update mysql table from form with CI" ?
how do I stop the foreach from running if a checkbox has not been checked.
You don't have to stop the foreach from running if a checkbox has not been checked.
Because $editcustomer variable only contain checkbox checked.
How do I pass the array to the model correctly so that the update runs?
Your model is wrong. It should be:
public function update_customer_records($updatedrow)
{
$this->db->update('customers', $updatedrow);
}
You don't need to write $this->db->where('id',$this->input->post('id')); (and it's wrong, because you can't use $this->input->post() in your model) because you already pass id in $updaterow.
Edit : I'm sorry, I read your code too quickly!
function update_customer_records($updatedrow)
{
$this->db->where('id',$this->input->post('id'));
$this->db->update('customers',$updatedrow);
}
...is correct. Alternatively, you can write it in a shorter way:
function update_customer_records($updatedrow)
{
$this->db->update('customers', $updatedrow, array('id' => $this->input->post('id')));
}

dynamically load form in codeigniter

I am new to codeigniter trying out some simple pages. I have successfully connected to the database for inserting and updating. But now I want to populate the fields from the database for updating. That is when the user selects the name from the dropdown the corresponding values should appear in the other fields so that the user can update easily.
I have worked on this to do without ajax or jquery. It worked for me but with some warning message - Use of undefined constant.
I am giving by mvc. Help me clear this.

you can use Ajax for this purpose
onchange of your select box fill a div with form.
Controller Method
function getUserdata(){
$where['username'] = $this->input->post('username');
$this->load->model('users_model');
$data['user'] = $this->users_model->getUser($where);
$this->load->view('userform',$data);
}
And you model method
function getUser($where){
return $this->db->where($where)->get('usertable')->row()
}
Ajax
$(function(){
$('#selecttion').change(function(){
var username = $(this).val();
$.ajax({
url : '<?php 'echo url to controller method'?>',
type : 'POST' ,
data : 'username='+username,
success : function(data){
$('#dividtofill').html(data);
}
});
});
})
EDIT :
calling ajax is easy
for this include jquery library in your header.
Here is your dropdown
Note : put the above ajax code in your head section in script
<select name="user" id="selecttion">
<option value="John">John</option>
<option value="Sam">Sam</option>
<option value="David">David</option>
</select>
Now when this dropdown value is changed the ajax function defined above will be called.
I have finally cleared the error. I have done this by a simple if isset loop.
Now my get_row() in my model looks like this.
public function get_row() {
$data = array();
$id= 0;
if(isset($_POST['product_type_id'])){
$id = $_POST['product_type_id'];
}
$query = $this->db->get_where('product_type', array('product_type_id' => $id));
if ($query->num_rows() > 0) {
foreach ($query->result_array() as $row){
$data[] = $row;
}
}
$query->free_result();
return $data;
}
