I have form select with 2 values of 0 and 1
<select class="form-control form-control-sm col-sm-3" name="status">
<option value="1">On<option>
<option value="0">Off</option>
</select>
Now in codeigniter controller i set rule to accept only values of 0 or 1, so i used in_list[] function, but when i select Off i get error The Status field must be one of: 0,1., and when i select On i don't get any error.
Here is controller code
$this->form_validation->set_rules('status', 'Status', 'trim|required|xss_clean|in_list[0,1]');
if ($this->form_validation->run() === false) {
$data = [
'error' => true,
'status_error' => form_error('status')
];
}
echo json_encode($data);

<datalist id="stoplist">

[2] => Array

</datalist>
This is my view
foreach ($data1 as $row) {
echo "<option value=".$row['stops'].">".$row['stops']."</option>";
}
When I select katraj dairy I get only katraj as a value.
I am getting correct value from database as I print above. What is the problem?
From your controller you need to pass data from your controller before you can access it from your view.
&this->load->view("viewname.php",$data)
Where $data is the array you get from your database
format for select option
<select>
<option value="">name</option>
</select>
Modified code:
echo "<select>";
foreach ($data1 as $row) {
echo "<option value=".$row['stops'].">".$row['stops']."</option>";
}
echo "</select>";
I am creating a form with a many-many relationship. I have a posts table and an activities table. There is a many to many link using pivot table. I am creating a form to add one or more activities to the posts. I am receiving an 'ErrorException' - Trying to get property of non-object. I cannot understand why this is not working.
I would be grateful for any assistance you can offer me.
My relevant code is below.
//Posts/create.blade.php
{!!Form::open(['action' => 'PostController#store','method' => 'POST', 'class'=>'form-group'])!!}
{{Form::bsText('title','',['placeholder' => 'Trip Name'])}}
{{Form::bsTextarea('body','',['placeholder' => 'Trip Description'])}}
{{Form::bsSubmit('submit')}}
{{Form::label('activities', 'Activity:') }}
<select class="form-control select2-multi" name="activities" multiple="multiple">
#foreach($activities as $activity)
<option value="{{ $activity->id }}">{{ $activity->activity_name}}
</option>
#endforeach
</select>
{!! Form::close() !!}
// PostsController
public function create()
{
$activities = Activity::all();
return view('posts.create')->withActivities($activities);
$posts = Post::all();
}
public function store(Request $request)
{
// Create a new post using the request data
// Save it to the database
$this->validate(request(), [
'title' => 'required',
'body' => 'required',
]);
$post = Post::create([
'title' =>request('title'),
'body' =>request('body'),
'user_id' => auth()->id(),
'activity_id' => id()
]);
// And then redirect to somewhere in application
return redirect()->route('posts.show', $post->id);
}
This error throw only when you have empty variable but you point in blade file to render / display for browser. Or if you retrieve records from DB then add findOrFail in query to prevent those kind of issues. Thank you.
I'm using the framework Phalcon. I'm trying to create a form to get a value (an ID called "idcliente") from a table (in mysql) called cliente, which has 2 columns: "idcliente" and "nombre". With this value I want to update a field (also "idcliente") on another table called Users.
My form is this:
class AsignarclienteForm extends Form{
public function initialize($entity = null, $options = null){
$idcliente = new Select('idcliente',[
Cliente::find(),
"useEmpty" => true,
"emptyText" => "Please select...",
"using" => ["idcliente", "nombre"],
]);
$idcliente->setLabel('ID Cliente');
$idcliente->addValidators(array(
new PresenceOf(array(
'message' => 'idcliente is required'
))
));
$this->add($idcliente);
}
}
And my controller:
public function asignarclienteAction(){
$auth = $this->session->get('auth');
$permiso = $auth['active'];
$id = $auth['id'];
if($permiso!='A'){return $this->forward('servicios/index');}
$form = new AsignarclienteForm;
if ($this->request->isPost()) {
$idcliente = $this->request->getPost('idcliente');
$sql = "UPDATE Users SET idcliente = ?0 WHERE id = ?1";
$this->modelsManager->executeQuery($sql, array(0 => $idcliente, 1 => $id));
return $this->forward('admin/usuarios');
}
$this->view->form = $form;
}
And my view:
<div class="panel-body">
{{ form('admin/asignarcliente/', 'id': 'asignarclienteForm', 'onbeforesubmit': 'return false') }}
<fieldset>
<div class="control-group">
{{ form.label('idcliente', ['class': 'control-label']) }}
<div class="controls">
{{ form.render('idcliente', ['class': 'form-control']) }}
</div>
</div>
<div class="form-actions">
{{ submit_button('Asignar', 'class': 'btn btn-primary', 'onclick': 'return SignUp.validate();') }}
</div>
</fieldset>
</form>
</div>
I got the following error in the web site:
ID Cliente
Catchable fatal error: Object of class Phalcon\Mvc\Model\Resultset\Simple could not be converted to string in C:\xampp\htdocs\OpinionZoom\cache\volt\c%%%%xampp%%htdocs%%opinionzoom%%app%%views%%admin%%asignarcliente.volt.php on line 31
Where line 31 is {{ form.render('idcliente', ['class': 'form-control']) }}
on my view
I haven't found enough documentation of how to create a form with select, despite I have created a lot of forms.
If someone could help me I would appreciate it a lot. Thanks.
Your element definition in your form Asignarclienteform is incorrect.
The first parameter of Select must be a string (the name of your element).
The second parameter takes the options of your select element.
// Select construct parameters
Select(string $name, [object | array $options], [array $attributes])
I moved idcliente out of the array into the first parameter position:
$idcliente = new Select('idcliente', Cliente::find(), [
"useEmpty" => true,
"emptyText" => "Please select...",
"using" => ["idcliente", "nombre"],
]);
I've got a complicated re-population system that works, but it's cumbersome.
I've got a dropdown menu for a country of birth, and when the users submit the form it gets thrown in a database. The dropdown menu then gets repopulated with whatever is in the database if there is something.
I get the value from the database like this:
$birthplacecountry = (!set_select('birthplacecountry') && $birth_citizenship) ? $birth_citizenship[0]['birthplacecountry'] : (set_select('birthplacecountry') ? set_select('birthplacecountry') : '');
That works fine, as I've then got my options looking like this:
<option value="Afganistan" <?php if ($birthplacecountry == 'Afganistan') echo 'selected="selected"';?>>Afghanistan</option>
<option value="Albania" <?php if ($birthplacecountry == 'Albania') echo 'selected="selected"';?>>Albania</option>
<option value="Algeria" <?php if ($birthplacecountry == 'Algeria') echo 'selected="selected"';?>>Algeria</option>
<option value="American Samoa" <?php if ($birthplacecountry == 'American Samoa') echo 'selected="selected"';?>>American Samoa</option>
However, it's annoying having to compare $birthplacecountry to the name of the value manually. Is there a general way to compare something to the options value?
Some sort of functionality that works like: if ($birthplacecountry == this.option.value)
In codeIgniter, you should use Form helper to produce a select/dropdown, i.e.
$options = array(
'Afganistan' => 'Afganistan',
'Albania' => 'Albania',
);
echo form_dropdown('birthplacecountry', $options, 'Albania');
In this example, a dropdown with name birthplacecountry will be created and selected option will be Albania, the seconf one. The third parameter sets the selected option, so, when you want to repopulate the form with selected option, you can do something like this
echo form_dropdown('birthplacecountry', $options, set_select('birthplacecountry', $this->input->post('birthplacecountry') );
I'm trying to get the option item selected in a form select element using Codeigniter...
I have a controller named results with this code in it
//get form data
if($_SERVER['REQUEST_METHOD'] == "POST"){
$data['searchdata'] = array(
"ionum" => $this->input->post('ionum'),
"thisdb" => $this->input->post('thisdb')
);
}
which loads into a view, the 'ionum' is a text input which I can retrieve, the 'thisdb' is the select, I get no results for it...how do I pull that?
Ensure your html looks like:
<form action="<?= site_url('mycontroller/myfunction');?>" method='post'>
<input type='text' name='ionum'/>
<select name='thisdb'>
<option value='db1'>DB1</option>
<option value='db2'>DB2</option>
</select>
</form>
Then in your controller, you would write:
class Mycontroller extends CI_Controller{
function myfunction(){
$p = $this->input->post();
if($p){
//you can now access the ionum and thisdb... try echo
echo $p['ionum'];
echo $p['thisdb'];
}
}
}
It is unnecessary to run the if($_SERVER['REQUEST_METHOD'] == "POST") conditional. Just check if $p exists as above.
