importing from mysql column to checkbox php - php

Question

i am trying to import from mysql column as an exploded values (category id) from table called "products", and print it in a checkbox input, and check if the value (category id) equal to the (category id) in the table called "cats", to set checkbox to "checked", this is my code:
<?php
for($i2=0;$i2<$rowsZ22;$i2++){
//exploding
$catszz2 = explode(",", $bussSubcat);
//foreach start
foreach($catszz2 as $catzz2) {
if($catzz2==$row22[$i2]["id"]){
$ischecked2="checked";
}else{
$ischecked2="";
}
}
//foreach end
?>
<li><input type="checkbox" onclick="getElementById('cats<?=$row22[$i2]["parent"]?>').checked= true;" <?=$ischecked2?> value="<?=$row22[$i2]["id"]?>" name="subcats[]" id="" /> <?=$row22[$i2]["title"]?></li>
<?php
}
?>
the code is checking the last input only (last category)
any help ?

Answer 1

You're running a foreach before you actually output the checkbox...
So, the $isChecked variable is actually changing in your foreach, but only the last value of the loop will be printed.
You need to move your
<li></li>inside the loop of the $isChecked
I'm not sure if this is what you want, but here goes:
<?php
for ($i2 = 0; $i2 < $rowsZ22; $i2++) {
$catszz2 = explode(",", $bussSubcat);
foreach ($catszz2 as $catzz2) {
if ($catzz2 == $row22[$i2]["id"]) {
$ischecked2 = "checked";
} else {
$ischecked2 = "";
}
?>
<li>
<input type="checkbox"
onclick="getElementById('cats<?= $row22[$i2]["parent"] ?>').checked= true;" <?= $ischecked2 ?>
value="<?= $row22[$i2]["id"] ?>" name="subcats[]" id=""/> <?= $row22[$i2]["title"] ?>
</li>
<?php
}
}
?>
