Loop/Count Output Display Help
Asked Modified Viewed 820 times

I have this quirky problem/need in my bootstrap_tabs infusion. First of all I took code from my Avatar Studio to read the uploaded images directory to get the uploaded filenames. Here is the function. ...and here is the page/portion where it is used.Here are 2 images of the resultant output (tbl1.jpg) and what I need it to be (tbl2.jpg). Of course the cells would all be the same width on tbl2.jpg; this is just an image.
I can't figure out how to code the script to generate rows of 6 images. I know this should be a simple matter of looping and counting but I haven't been able to get it to work right.
Code Download source
function loadTabImgs($dir) {
$ignoreTabImgs = '.|..|.htaccess|index.php|.tmp';
$tab_images = makefilelist(TAB_FOLDER.$dir, $ignoreTabImgs, true, 'files', '.png,.gif,.jpg,.jpeg');
return (isset($tab_images)) ? $tab_images : false;
}Code Download source
$tab_images = loadTabImgs(TAB_FOLDER);
if (is_array($tab_images) && count($tab_images) > 0) {
echo "<div align='center'><h4><strong>Uploaded Image Names For Textarea</strong></h4></div>n";
echo "<div align='center'><table align='center' border='1'><tr>n";
$i = 0;
foreach($tab_images as $img_name) {
echo "<td><b>$img_name</b></td>n";
$i++;
}
}
echo "</tr></table></div>n";I can't figure out how to code the script to generate rows of 6 images. I know this should be a simple matter of looping and counting but I haven't been able to get it to work right.

Based on the counter $i mod 6 = 0 insert a </tr> <tr>

OK; got it figured out. There's probably an easier way to do it but this works just fine and does not generate errors at all on 9.10.20. I really can't see anyone ever uploading more than 24 images for the tabs. Here is the output image.

$tab_images = loadTabImgs(TAB_FOLDER);
if (is_array($tab_images) && count($tab_images) > 0) {
echo "<div align='center'><table align='center' border='1'><tr>n";
echo "<td bgcolor='#840000' colspan='6' align='center'><span style='color:white;'><h4><strong>Uploaded Image Names For Textarea</strong></h4></span></td></tr><tr>n";
$i = 1;
foreach($tab_images as $img_name) {
echo "<td bgcolor='#B7DBFF' align='center'><b>$img_name </b></td>n";
if ($i == 6 || $i ==12 || $i ==18) {
echo "</tr><tr>n";
}
$i++;
}
}
echo "</tr></table></div>n";Edited by Grimloch on 12-04-2022 20:51,

If you replace ($i == 6 || $i ==12 || $i ==18) by ($i % 6 == 0)
Then it works for every multiply of 6
That's what I meant
