Show only Images from News List...

[Cyberdave]

I am using Concrete5 on a site I'm working on. Below is the News List display view.php file needed in the block to display the content from news pages. The code allows images entered in the WSYIWYG to appear in the RSS list. I want to know how I can edit the code below, so it shows only the these images from the $content not the text. Can anybody help me on this? Thanks

   	$pageno = $_GET['pageno'];

   	$pageno = 1;

Can anyone help me on this?

OK, I have got the images to appear using the following code:

 

<div class="description">
<?php {preg_match_all('/<img[^>]+>/i',$content,$images);} print_r($images); ?></div>

 

However, the Array info is appearing between the images, like this: Array ( [0] => Array ( [0] => 07-Green.gif [1] => 05-Red.gif [2] => 21-Yellow.gif [3] => 20-Blue.gif ) )

 

How can I edit the code so that only the images appear, without the array details? Thanks

print_r is used to show the values of an array

 

lets assume $images is the array.

 

or can be looked at as array($images)

 

foreach ($images as $image) {
echo $image;
}

 

 

[Cyberdave]

So is this the correct code?

 

<div class="description">
<?php {preg_match_all('/<img[^>]+>/i',$content,$images);} print_r($images);
foreach ($images as $image) { echo $image; } ?></div>

[QuickOldCar]

I see no reason for this part

 

 print_r($images);

[Cyberdave]

My code is like this now, but now the images do not appear:

 

<div class="description">
<?php preg_match_all('/<img[^>]+>/i',$content,$images);
foreach ($images as $image) { echo $image; } ?></div>

[Cyberdave]

This has solved my problem. 

 

<div class="description">
<?php preg_match_all('/<img[^>]+>/i',$content,$images); ?> <?php foreach($images[0] as $img){ echo $img;}?></div>
