I have the below section of code and I want to only show the html IF the ID is set in the url. It isn't working and I am not sure why! The same code works on other areas of the page just not here! I am editing some code that someone else built for me, I am a php noob so please bear with me!
Thanks for any help!!
<?php if(!isset($_GET['id'])) { ?>
<div class="control-group"> Show this text </div>
<? } ?>
You have your conditional the wrong way round.
<?php if(isset($_GET['id'])) { ?>
<div class="control-group"> Show this text </div>
<?php } ?>
You have to remove the not (!), obviously. As the logic you want is isset and not not isset.
Try this:
<?php if(isset($_GET['id'])) {
echo "<div class='control-group'> Show this text </div>";
}; ?>
Depending if you want to show the code or not place a ! in front of isset.

I would like to detect a certain category with ID=4 and then apply if/else to add div to display contents.
<?php
if (JRequest::getVar('view')=='categories' && JRequest::getVar('id')==4) { ?>
<?php } ?>
How do I achieve this?
I want to show this if the article belongs to category 4 else show another div.
Imagining this two be the different div
<div class="category4">text here</div>
<div class="categoryxxx">text here</div>
Do note that <?php echo $this->item->catid;?> shows the correct Category ID. I would like to apply if and else statement using catid==9 or something. Just not good at PHP.
You can also put directly the html code, avoiding echo. It may useful especially when html code is sizeable.
<?php if ($this->item->catid == 4): ?>
<div class="category4">text here</div>
<!--- any other html code --->
<?php else: ?>
<div class="categoryxxx">text here</div>
<!--- any other html code --->
<?php endif; ?>
Hey I got it working :)
<?php
if ($this->item->catid == 9) {
echo "yes, it exists";
}
else {
echo "no, it don't exist";
}
?>
I have this site:

I installed the plugin Types and tried this code to display the value field in a div.
<div class="selectat">
<div>
<?php $variable = do_shortcode("[types field='descriere' ]");?>
<?php echo $variable;?>
</div>
</div>
My field is called descriere..I put a picture to see more clearly.
Unfortunately this blank although I do not see anything on the site and basically my div is empty ..
It is wrong the way I wrote the code?
I must call another function?
You can help me solve this problem please?
Thanks in advance!
You dont need to use any shortcode you could use
<div class="selectat">
<div>
<?php $variable = the_field( 'descriere' );
<?php echo $variable;?>
</div>
</div>
But if you want to echo the code straight away you can just use get_field('') which echos the value straight to the page.
<div class="selectat">
<div>
<?php $variable = get_field( 'descriere' );
</div>
</div>
I'm very newbie regarding PHP, I'm trying to configure my wordpress Loop.
I figured out how to display my customfield in my template, I manually added a title before my taxonomy and custom fields, but I'd like it doesn't show if the taxonomy is empty.
Here is the code:
<div class="customfields">
<h2 class="widgettitle">My Title</h2>
<?php echo do_shortcode('[tax id="agences" before="Agences : " separator=", " after=""]'); ?>
<?php echo do_shortcode('[custom_fields_block]'); ?>
</div>
I would very much appreciate your help!
Thanks a ton,
T.
So code should be
<?php $taxonomy = do_shortcode('[tax id="agences" before="Agences : " separator=", " after=""]'); ?>
<div class="customfields">
<?php if(!empty($taxonomy)) : ?>
<h2 class="widgettitle">My Title</h2>
<?php echo $taxonomy; ?>
<?php endif; ?>
<?php echo do_shortcode('[custom_fields_block]'); ?>
</div>
If you want to show content in HTML only if certain variables contain a value then you can create a simple if statement that uses PHP's isset function to determine whether or not the variables are set, and if true place some HTML on the page. You can read more about isset here.
I have a PHP page with HTML content in it. Now I run some PHP codes between HTMLs and I get some results. The fact is, when I try to get a respond from this page by AJAX it'll show me the whole page content and plus the result I was looking for. What can I do to prevent the page from writing extra content. I know whenever something get printed on page it'll go as respond to the AJAX call but I want a way to somehow fix this.
My page file (name: page.php):
<?php echo $Content->GetData('HEADER'); ?>
<div id="Content">
<div id="Page">
<?php if($Content->GetData('PAGE','IS_TRUE')) : ?>
<?php if(NULL !== $Content->GetData('PAGE','TITLE')) : ?>
<?php echo $Content->GetPlugins("Page:" . $Content->GetData('PAGE','ID') . ",BeforeTitle"); ?>
<div id="Title" dir="rtl">
<?php echo $Content->GetData('PAGE','TITLE'); ?>
</div>
<?php echo $Content->GetPlugins("Page:" . $Content->GetData('PAGE','ID') . ",AfterTitle"); ?>
<?php endif; ?>
<div id="Content" dir="rtl">
<div style="float: right; width: 966px; padding: 6px">
<?php echo $Content->GetPlugins("Page:" . $Content->GetData('PAGE','ID') . ",BeforeContent"); ?>
<?php echo $Content->GetData('PAGE','CONTENT'); ?>
<?php echo $Content->GetPlugins("Page:" . $Content->GetData('PAGE','ID') . ",AfterContent"); ?>
</div>
</div>
<?php else : ?>
<div id="Content" dir="rtl">
<div style="float: right; width: 966px; padding: 6px">
There is no page like this in our archives.
</div>
</div>
<?php endif; ?>
</div>
</div>
<?php echo $Content->GetData('FOOTER'); ?>
If I write an address in my browser like this localhost/cload/blog?action=rate it'll go through my redirection list and show the page.php with blog plugin loaded. The problem is I want to call my blog plugin by AJAX through this address but it will first render the page data.
Sorry if this is messy.
I'd suggest modifying page.php to be some functions, primarily a data processing function, and then an output function. Then, when you load the page, put a check in for whether it's an AJAX request, and if so, echo the data you want as JSON, otherwise render the page using the output function.
Alternatively, you could create a second, separate page, but that could be more difficult to maintain than a single file.
Yes, you should check whether your request is a ajax request, if it is so you should change your response to return only the result whatever want.
This php code will give an rough idea on this.
if($request->isXmlHttpRequest()){
return new Response(json_encode($data_array));
}
Hope this will help.
I'm using the following section of code to display some icons on our Magento store with the idea being if there is nothing added in the icons section it shouldn't display, for some reason this isn't working...it is displaying a division as if something is there but there is actually nothing.
<?php
if($_helper->productAttribute($_product,($_product->geticons()), 'icons') !== null):
?>
<div class="product-icons">
<?php echo $_helper->productAttribute($_product,($_product->geticons()), 'icons') ?>
</div>
<?php endif; ?>
It needs to show Icons if they are coded in the attribute field and then hide the division if there is nothing added.
I've worked out that the code is returning a value of string(0) what do I need to change in my coding to get the desired effect?
Here's the thing you need, and you don't need call the same functionality twice to get the empty result. Define your variable and check if it is empty (null, undefined or false) or not
<?php $icons = $_helper->productAttribute($_product,($_product->getIcons()), 'icons');?>
<?php if(!empty($icons)):?>
<div class="product-icons">
<?php echo $icons;?>
</div>
<?php endif;?>
this could be even better solution as it wont call the helper unless there are icons defined but you first have to try it out on your codebase.
<?php if($_product->getIcons()):?>
<div class="product-icons">
<?php echo $_helper->productAttribute($_product,($_product->getIcons()), 'icons') ?>
</div>
<?php endif; ?>
and please check if it isn't a typo and it really is:
$_product->geticons()
or should it be
$_product->getIcons()
Something like:
<?php
if($_helper->productAttribute($_product,($_product->geticons()), 'icons'))
{
echo "<div class=\"product-icons\">";
echo $_helper->productAttribute($_product,($_product->geticons()), 'icons');
echo "</div>";
}
?>
would be better!
try
<?php
if(!empty($_helper->productAttribute($_product,($_product->geticons()), 'icons')))
{
echo "<div class=\"product-icons\">";
echo $_helper->productAttribute($_product,($_product->geticons()), 'icons');
echo "</div>";
}
?>
