获取第一个/一个$ item-> image JOOMLA

Question

I have a problem on my Joomla website. This is the code I am having some trouble with:

 echo '<div style="background: url(/images/'.$item->image.');"></div>';

This is the URL I get if my article only has one image inside:

 <div style="background: url(/images/my_image.jpg);"></div>

This is the URL I get if my article has multiple images inside:

 <div style="background: url(/images/my_image.jpg my_image2.jpg);"></div>

Both images are being picked up even if I only need one.

Answer 1

you can do it with the is_array function:

if(is_array($item->image)) {
 echo '<div style="background: url(/images/'.$item->image[0].');"></div>';
} else {
 echo '<div style="background: url(/images/'.$item->image.');"></div>';
}

Answer 2

Use the explode function to make the string an array, and then access the first item in the array…

$imageArray = explode(" ", $item->image);
echo '<div style="background: url(/images/'.$imageArray[0].');"></div>';

This of course assumes that if there are multiple images, you always want the first.
