foreach with array issue

[samtwilliams]

For some reason it will only show one result. when ther are multiple in my array.

 

My array data

Array ( [0] => Array ( [CD0002] => 7 ) [1] => Array ( [CD0004] => 5 ) [2] => Array ( [CD0006] => 12 ) ) 

 

My array

<?PHP 
$itemarrayview = $_SESSION['ItemTotalArray'];
foreach($itemarrayview[0] as $key => $value) {
echo '<tr>'; 
echo '<td>'.$key."</td>";
echo '<td>'.$value."</td>";
echo '<td align="center"><a href="pt_allocate.php?remove='.$key.'&asi='.$ASI_index.'">Create</a></td>';
echo '</tr>'; 
}
?>

that would be because $itemarrayview[0] is only one record...

I see that now, but struggling to fix it, if i place it within another foreach loop it works but then all my data elements become offset and i cant seem to fix them

[samtwilliams]

I now have this;

 

<?PHP 
$itemarrayview = $_SESSION['ItemTotalArray'];
unset($i);
$i = 0;
foreach ($itemarrayview as $key => $value) {
foreach($itemarrayview[$i] as $key => $value) {
echo '<tr>'; 
echo '<td>'.$key."</td>";
echo '<td>'.$value."</td>";
echo '<td align="center"><a href="pt_allocate.php?remove=1&asi='.$ASI_index.'&offset='.$i.'">Remove</a></td>';
echo '</tr>';
}
$i++; 
}
?>

 

which echo's my multidimensional array in a table, the only thing is if i remove one of them when i remove another i get offset errors everywhere.

 

Anyone kind enough to help?

 

Thanks

Don't use "$key" & "$value" for both foreach loops.

Thanks Ken,

 

I have changed that which has relieved the main issue, except how do i return the array key value, as I need it to remove elements using my remove link, as you can see i use $i in the link but thats not correct if there is 1 element in the array.

 

$itemarrayview = $_SESSION['ItemTotalArray'];
unset($i);
$i = 0;
foreach ($itemarrayview as $value) {
foreach($value as $key => $value) {
echo '<tr>'; 
echo '<td>'.$key."</td>";
echo '<td>'.$value."</td>";
echo '<td align="center"><a href="pt_allocate.php?remove=1&asi='.$ASI_index.'&offset='.$value.'">Remove</a></td>';
echo '</tr>';
}
$i++; 
}

You're still using the variable $value twice:

<?php
foreach ($itemarrayview as $value) {
   foreach($value as $key => $value) {
?>

Change it to

<?php
foreach ($itemarrayview as $v) {
   foreach($v as $key => $value) {
?>

And then decide which $value you want to use in your code.

Have just changed that but still cant work out how to return the key from the first array to go in my removal link.

[kenrbnsn]

Please post you're current script.

[samtwilliams]

$itemarrayview = $_SESSION['ItemTotalArray'];
unset($i);
$i = 0;
foreach ($itemarrayview as $v) {
foreach($v as $key => $value) {
echo '<tr>'; 
echo '<td>'.$key."</td>";
echo '<td>'.$value."</td>";
echo '<td align="center"><a href="pt_allocate.php?remove=1&asi='.$ASI_index.'&offset='.$i.'">Remove</a></td>';
echo '</tr>';
}
$i++; 
}

 

An example array data;

 

Array ( [1] => Array ( [CD0005] => 2 ) ) 

 

I want to put the first array Key ('1' in this example) into my remove link so i can use this code;

 

unset($_SESSION['ItemTotalArray'][$offset]);

 

Thanks Ken

It would help if you indented you code better. Change your first "foreach" and the echo line as seen below:

<?php
$itemarrayview = $_SESSION['ItemTotalArray'];
unset($i);
$i = 0;
foreach ($itemarrayview as $k => $v) {
foreach($v as $key => $value) {
	echo '<tr>';
	echo '<td>'.$key."</td>";
	echo '<td>'.$value."</td>";
	echo '<td align="center"><a href="pt_allocate.php?remove=1&asi='.$ASI_index.'&offset='.$k.'">Remove</a></td>';
	echo '</tr>';
}
$i++;
}
?>

 

BTW, this doesn't make any sense:

<?php
unset($i);
$i = 0;
?>

 

Just set $i to 0, without using the unset.
