Trim last item?

Hi Tim,

Try this :

<?php
    $str = array();
    foreach ($home_pageRecord['hero_image'] as $index => $upload) {
        $str[] = '{img: '. htmlencode($upload['urlPath']) .', caption: '. htmlencode($upload['info1']). '}';
    } echo implode(",", $str), "\n\n";
?>

Thanks!

Thanks Djulia.

I think you missed a bracket "(", but it's also trimming both commas, not just the last one?

<?php 

foreach ($home_pageRecord['hero_image'] as $index => $upload) {
echo rtrim('{img: '. htmlencode($upload['urlPath']) .', caption: '. htmlencode($upload['info1']). '},', ',');
}
?>

is returning

{img: /~thelakes/cmsb/uploads/s1.jpg, caption: This is slide 1}{img: /~thelakes/cmsb/uploads/s2.jpg, caption: heres another slide}];

and needs to return

{img: /~thelakes/cmsb/uploads/s1.jpg, caption: This is slide 1},{img: /~thelakes/cmsb/uploads/s2.jpg, caption: heres another slide}];

Oops! I am not really awaked!

I have the feeling which you wish to obtain from the data encoded in json.

Can you test this?

<?php
    $str = array();
    foreach ($home_pageRecord['hero_image'] as $index => $upload) {
        $str[] = '{img: '. htmlencode($upload['urlPath']) .', caption: '. htmlencode($upload['info1']). '}';
    }

    //echo json_encode($str, JSON_HEX_TAG | JSON_HEX_APOS | JSON_HEX_QUOT | JSON_HEX_AMP | JSON_UNESCAPED_UNICODE), "\n\n";
    echo json_encode($str), "\n\n";
?>

I corrected my proposal.

Hey Djulia.

I appreciate your help!

I am now getting the error: Notice: Array to string conversion in /home/thelakes/public_html/index.php on line 161Array];

If it helps, the complete code that I require is as below, and I'm trying to produce the highlighted.

<script>

var items = [
{ img: "image1.jpg", caption: "This is the first caption."},
{ img: "image2.jpg", caption: "This is the second caption."}
];

var images = $.map(items, function(i) { return i.img; });

$.backstretch(images);
$(window).on("backstretch.show", function(e, instance) {
var newCaption = items[instance.index].caption;
$(".caption").text( newCaption );
});

</script>

With the version json?

Can you state that there is on line 161?

Thanks!

Hi Tim,

Another way to do it is to check if the current array is the last item. If not, then add a comma.

For example:

$lastUploadRecord      = end($home_pageRecord['hero_image']); // get the last record
$imageAndCaptionString = '';
foreach ($home_pageRecord['hero_image'] as $index => $upload){
  $imageAndCaptionString .= '{img: "'.htmlencode($upload['urlPath']).'", caption: "'.htmlencode($upload['info1']).'"}';
  if ($upload['num'] != $lastUploadRecord['num']){
    $imageAndCaptionString .= ','; // add comma if this is not the last upload record
  }
}
showme($imageAndCaptionString);

Let me know if that works for you.

Thanks,

Hey Daryl - that worked thanks!  I changed showme($imageAndCaptionString); to echo($imageAndCaptionString);
