Warning: Illegal string offset 'id'

Question

I have defined two variables as follows:

$pic = get_tax_meta($books->term_id,'books_field_id', true);
$imageurl = wp_get_attachment_image_src( $pic[id], 'list-thumb' );

print_r($pic) results in the following:

Array ( [id] => 302 [src] => http://localhost/mysite/wp-content/uploads/2013/10/apic.jpg )

However, I get the following warning from $pic[id]:

Warning: Illegal string offset 'id'

Any idea what I'm doing wrong?

This seems to have fixed the problem:

$pic = get_tax_meta($books->term_id,'books_field_id', true);
if (isset($pic['id'])) {
      $picid = $pic['id'];
};
$imageurl = wp_get_attachment_image_src( $picid, 'list-thumb' );

You need to wrap the array key in quotes like the following.So This

$pic[id]

Must be

$pic['id']

Or

$pic["id"]

I still get the same warning with or without quotes (single or double) – user1444027 Oct 28 '13 at 14:14
Does the Key Actually exist? – Justin E Oct 28 '13 at 14:18
It does for some, for others (if a picture hasn't been uploaded) it doesn't exist – user1444027 Oct 28 '13 at 14:35

You need to wrap id in either single or double quotes:

$pic["id"]

Or:

$pic['id']

See Accessing array elements with square bracket syntax for more detail.

Replace

 $imageurl = wp_get_attachment_image_src( $pic[id], 'list-thumb' );

with

 $imageurl = wp_get_attachment_image_src( $pic["id"], 'list-thumb' );
