 * **The Problem:** I’m trying to remove photo thumbnails from my main pages. I 
   want only text there. Then I want the photo to show up on the actual single post
   url when they have clicked through there.
 * Customize Page does not work on my script. Developer will not explain why. Nor
   does he want to help or answer e-mails. So I’m stuck trying remove this PHP code
   that I don’t even know what looks like or where it is.
 * I read in forum that it should be under single dot php but it’s not in my theme.
   Any idea what code I am looking for and what it may look like?
 * I assume it’s called thumbnail or photo or image.
 * Any help would be much appreciated. I’ve had so many problems with this theme
   and there are so many things I’ve had to just forget about because it doesn’t
   function properly. This however I can’t overlook and I must fix it.

   working. Not event ext showed up.

 * Since it is a commercial theme, I will not be able to tell you the exact code
   that needs to be modified, but I can hopefully give you the right hints
    - Open content.php and search for the function `get_the_post_thumbnail`
    - Add an if around it to check if it is the home page. Something like this `
      <?php if(!is_home() && !is_front_page()) get_the_post_thumbnail(); ?>`
 * Hope this helps.

 * Hey the code is clear. Thank you for answering 😉
 * There is no content PHP file.
 * Why is there a rule against helping someone modify something they’ve bought?
 * If you had a Samsung TV and wanted to rebuild it into a fridge I think Samsung
   could not sue me for helping you with that 😉
 * Jokes aside. I’m searching through all php files now for thumbnail text but not
   sure what I’m looking for. This is confusing. Thank you for trying though.
 * Your post was like Greek to me.

 * Do you think this is it? Is there a small thing I can take off int hat code which
   would make script still work? I’m so afraid to modify things lest I destroy everything.
   Been working on this nonstop for a week now.

       // Post thumbnail generator
   
       	function mamontov_post_thumb($id, $size='preview') {

 * Under page PHP there is something I thought might help so I removed the whole
   4th line but it didn’t have any effect.
 *     ```
       <?php get_header(); ?>
   
       <div class='posts page'>
   
       	<?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>
   
       		<?php echo mamontov_post_thumb($post->ID); ?>
   
       		<div class='inside-post-wrap'>
   
       			<?php if(!is_front_page()) { ?>
   
       					<h2 class='post-title'>
       						<?php the_title(); ?>
       					</h2>
       ```

 * Not a hard-fast rule IF someone here is able and willing to help, but here’s 
   the details about that:

 * I am not against helping fix issues/make changes in commercial products, but 
   without access to the code, I might end up barking up the wrong tree (just like
   I did here).
 * However, the function you identified `mamontov_post_thumb` is right on spot. 
   Here is a quick fix: Add these line at the start of the function (right after
   the line `function mamontov_post_thumb...`)
 *     ```
       if (is_home() || is_front_page()) {
       	return null;
       }
       ```
   
 * Basically, at the start of the function, you check if it is the home or front
   page and you return an empty value.

 * thecodeisclear, thank you for replying. I feel a solution may be in reach. I 
   tried many varieties of your code:
 *     ```
       <?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>
   
       		<?php echo mamontov_post_thumb($post->ID) if (is_home() || is_front_page()) {
       	return null;
       }; ?>
   
       		<div class='inside-post-wrap'>
       ```
   
 * and
 *     ```
       <?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>
   
       		<?php echo mamontov_post_thumb($post->ID); ?>
   
       if (is_home() || is_front_page()) {
       	return null;
       }
   
       		<div class='inside-post-wrap'>
   
       			<?php if(!is_front_page()) { ?>
       ```
   
 * and this
 *     ```
       <?php echo mamontov_post_thumb if (is_home() || is_front_page()) {
       	return null;
       } ($post->ID); ?>
   
       		<div class='inside-post-wrap'>
   
       			<?php if(!is_front_page()) { ?>
       ```
   
 * But the pictures still remain and nothing changes. Of course this is some ridiculous
   mistake I’m making but I just don’t see it. Could it be this is the wrong PHP
   file? or am I using the code you gave me the wrong way?
 * Again thanks for helping me.

 * I even tried removing the whole mamontov_post_thumb code from the text below 
   and updated. The images were still there.
 *     ```
       ( have_posts() ) while ( have_posts() ) : the_post(); ?>
   
       		<?php echo mamontov_post_thumb($post->ID); ?>

 * Hey, so I was experimenting with PHP editing and now my whole site is down. I
   cannot even access wordpress and my site won’t load. I just get this message 
   on the screen:
 * Parse Error Syntax Error, unexpected if:
 * How do I solve this if I can’t even log in to wordpress and install theme again?

 * ok, after re-uploading a backup of the file in FTP I was able to get site up 
   and running again but back to square one now. At least wordpress is working again.
 * Can you guys recommend someone I can hire to solve this issue?

 * Hi,
 * Sorry, I think I was not clear where to make the change. You need to make the
   change in the same file which you pasted in [reply#4](https://wordpress.org/support/topic/how-to-find-php-code-in-custom-script?replies=15#post-6825100)
 * What I have suggested is to modify the theme function that creates the post thumbnail
   to return nothing when it is called from the home page. Please don’t make any
   changes to any other files where the function is being called from (For e.g. `
   <?php echo mamontov_post_thumb($post->ID); ?>`)
 * Cheers,
    Ramesh
