I want to display 'Hi' using Simple HTML DOM from a URL.
Do you want to see something like this?
$el = $html->find("#first", 0);
while ($child = $el->children(1)) {
$el = $child;
}
echo $el->innertext;

I am trying to add two forms in my ejs page using ajax-form tags and sails.js 1.0.0. Can you have multiple tags inside one ejs page? In the first form the action is updateMaplayers which looks at the controller update-maplayers.js file to update any records and the maplayers action on the second ajax-form looks at the maplayers.js controller to add a new record. When I try to run either actions they both fail if I have both . If I remove one of the ajax-form actions I I can submit. Does anyone have any examples?
My ejs file looks like
<div id="maplayers-main" v-cloak>
<div class="container" >
<div class="row">
<div class="col-sm-6">
<h1>Map Layers</h1>
</div>
<div class="col-sm-6">
<button type="button" class="btn btn-outline-primary float-right" #click="openAddMapLayerForm()">Add</button>
</div>
</div>
<hr/>
<div id="maplayers-container" >
<% _.each(maplayers, function (maplayer) { %>
<ajax-form action="updateMaplayers" :syncing.sync="syncing" :cloud-error.sync="cloudError" #submitted="submittedForm()" :handle-parsing="handleParsingForm">
......
</ajax-form>
<% }) %>
</div>
<div id="maplayers-add-container">
<ajax-form action="maplayers" :syncing.sync="syncing" :cloud-error.sync="cloudError" #submitted="submittedForm()" :handle-parsing="handleParsingForm">
........
</ajax-form>
</div>

All of my content elements are wrapped using stdWrap.wrap.
I am looking for a solution to wrap content elements in the page which i have my ke_search added differently .
Why do you need another HTML-markup?
Normaly you have another <div> around your search results which should enable you to add another styling by CSS.
your page may look like:
<body>
<div class="header">
:
</div>
<div class="content">
<div id="C123">
<h3>my very special CE</h3>
<p class="bodytext">with some text to demonstrate.</p>
</div>
<div id="345">
<h3>your search results:</h3>
<div class="search-results">
<a href="index.php?id=67&s=special">
<div id="C123">
<h3>my very special CE</h3>
<p class="bodytext">with some text to demonstrate.</p>
</div>
</a>
<a href="index.php?id=83&s=special">
<div id="C52">
<h2>just a demo</h3>
<p class="bodytext">this text is nothing special.</p>
</div>
</a>
</div>
</div>
</div>
</body>
with appropiate CSS the first CE looks completely different to the same CE in the search results.
h3 { color:black; font-size:16px; }
p.bodytext { color:#444; font-size:12px; }
.search-results h3 { color:blue; font-size:10px; font-weight:bold; }
.search-results p.bodytext { color:#44b; font-size:10px; font-style:italics; }
I answer my own question:
You can conditionally wrap specific content elements using the following typoscript snippet.
tt_content {
stdWrap {
if.value = tx_kesearch_pi2
{
wrap = |
innerWrap >
}
wrap = <div class="someotherclass">|</div>
}
}
A page that I want to scrape data from has the following elements
<div class="content">
<p>I want this</p>
<p>I want this</p>
<div class="row">
<p>I do not want this</p>
<p>I do not want this</p>
</div>
</div>
I do not want paragraphs in the <div class="row">
This is what I have tried so far. Doesnt seem to work
foreach ($sample_html->find('div[class=entry-content]') as $content) {
foreach($content->find('div[class=row]') as $row){
foreach ($row->find('p') as $skip) {
$skip->outertext = '';
}
}
foreach($content->find('p') as $paragraph){
//echo $paragraph;
$paragraphs .= '<p>'.$paragraph->innertext.'</p>';
echo $paragraphs;
}
}
Change
$skip->outertext = '';
to
$skip->innertext= '';
I've never used code igniter and I'm trying to make a quick admin form that includes an image upload input. My admin form is up and has a route/url that I can reach, but the save function is not working correctly. I'm getting a 404 error when I click my submit button.
I believe the issue is with the line form_open_multipart('dashboard_save/do_upload') in views/admin/Dashboard.php. I don't think the do_upload function is being reached. Any ideas where I'm going wrong?
*new detail: I am able to reach my controller with form_open_multipart('dashboard_save') using an index function... but I'm not able to reach any other function such as form_open_multipart('dashboard_save/upload') using an upload function in controller dashboard_save.

Hi first to check your do_upload function has been called or not . if yes then to please check you have loaded in upload library or not . if not so please upload library and than to use below code
<?php defined('BASEPATH') OR exit('No direct script access allowed');?>
<!DOCTYPE html>
<body>
<div id="main-wrapper">
<div id="main-container">
<div id="main-body">
<div id='main-form-body'>
<p>Configure front end here.</p>
<div id='admin-form-container'>
<form id="admin-form" method="post" action="<?php echo base_url()?>/dashboard_save/do_upload" enctype="multipart/form-data">
<div class='form-field'>
<div class='label-wrapper'><label for='main_img'>Main Image</label></div>
<input type = "file" name = "userfile" size = "20" />

<div class='form-field'>

You have used two times the form tag. This is why its taking last one and showing error. Remove one FORM tag. Here is your view file code revised
<?php defined('BASEPATH') OR exit('No direct script access allowed');?>
<!DOCTYPE html>
<body>
<div id="main-wrapper">
<div id="main-container">
<div id="main-body">
<div id='main-form-body'>
<p>Configure front end here.</p>
<div id='admin-form-container'>
<?php $attributes = array('id' => 'admin-form'); echo form_open_multipart('dashboard_save/do_upload', $attributes);?>
<div class='form-field'>
<div class='label-wrapper'><label for='main_img'>Main Image</label></div>
<input type = "file" name = "userfile" size = "20" />
</div>
<div class='form-field'>

</div>
<?php echo form_close();?>
</div>

No test it. I have removed form open & close tag which you wrote manually, at same time use only form_open_multipart() & form_close() for accomplish same task
I tried to use the afterAdd binding to add some trivial animation to the elements being added to my observableArray but it does not trigger anything.
I tought I had a problem with my animation code so I coded a small alert on the function but still does not work.
Here's some sample code for the div being templated:
<div id="resultList"
data-bind='template: { name: "searchResultTemplate",
afterAdd: function(elem){alert(elem)} }'
runat="server">
</div>
This is the template:
<script type="text/html" id="searchResultTemplate">{{each(i, searchresult) resultCollection()}}
<div class="searchresultwrapper ui-corner-all ui-state-default">
<div class="searchresult">
<img src='${ ImageUrl }' alt='${ Title }' title='${ Title }' class="searchresultpicture" />
<div class="searchresultinformationcontainer">
<span class="searchresulttitle" data-bind="text: Title"></span>
<br />
<div class="searchresultdescription" data-bind="text: Description">
</div>
<span class="searchresultAuthor" data-bind="text: AuthorName"></span> at <span class="searchresultmodule" data-bind="text: ModuleName"></span> on <span class="searchresultdate" data-bind="text: PublicationDate"></span>
<br />
Take me there
</div>
</div>
</div>
<br />{{/each}}
</script>
Any ideas?
You need to qualify the template attributes with foreach like so,
<div id="resultList" data-bind='template: {
name: "searchResultTemplate",
foreach: searchresult,
beforeRemove: function(elem) { $(elem).slideUp() },
afterAdd: function(elem) { $(elem).hide().slideDown() }
}' runat="server">
</div>
and then, not use {{each in the template, just template it for each item stand alone.
Here, foreach attribute helps keep track of changes to the object array
