Array Not Returning Entire Element
Question by Bill
I think I simply have invalid syntax, but for the life of me I can’t figure it out. I have a nested array with 3 elements.
$screenshot = array( array( Carousel => "Library.png", Caption => "Long caption for the library goes here", ListItem => "The Library"));
I’m using a for loop to compose some HTML that includes the elements.
<?php
for ( $row = 0; $row < 4; $row++)
{
echo "<div class="feature-title"><a href=" . $carousel_dir . $screenshot[$row]["Carousel"] . " title=" . $screenshot[$row]["Caption"] . " rel="lightbox[list]">" . $screenshot[$row]["ListItem"] . "</a></div>";
}
?>
My problem is that the “title” portion of the “a” tag only includes the first word, Long. So in the above case it would be:
<div class="feature-title"><a href="/images_carousel/1A-Library.png" title="Long" caption for the library goes here rel="lightbox[list]" class="cboxElement">The Library</a></div>
Can anyone shed some light on my error? Thanks in advance.

You forgot double quotes around the attribute values, so only the first word counts. The rest become (invalid) attribute names.

Make a habit of wrapping, the array index within double-quotes i.e. " for string indexes.
$screenshot = array(
array(
"Carousel" => "Library.png",
"Caption" => "Long caption for the library goes here",
"ListItem" => "The Library")
);
