PHP Smarty Foreach Loop
I'm using smarty for my site, and I'm trying to loop through an array to print out table rows...
The array looks like this:
Array
(
[TM98800G] => Array
(
[zid] => Array
(
[0] => 90001
[1] => 90002
[2] => 90003
[3] => 90004
[4] => 90005
)
[count] => Array
(
[0] => 10
[1] => 10
[2] => 20
[3] => 25
[4] => 15
)
)
[TM76654G] => Array
(
[zid] => Array
(
[0] => 90301
[1] => 90302
[2] => 90303
[3] => 90304
[4] => 90305
)
[count] => Array
(
[0] => 25
[1] => 25
[2] => 20
[3] => 35
[4] => 45
)
)
)
I'm trying to loop through this and print out tables:
<h5>TM98800G </h5>
<table>
<tr>
<td>90001</td>
<td>10</td>
</tr>
<tr>
<td>90002</td>
<td>10</td>
</tr>
<tr>
<td>90003</td>
<td>20</td>
</tr>
<tr>
<td>90004</td>
<td>25</td>
</tr>
<tr>
<td>90005</td>
<td>15</td>
</tr>
</table>
<h5>TM76654G</h5>
<table>
<tr>
<td>90301</td>
<td>25</td>
</tr>
<tr>
<td>90302</td>
<td>25</td>
</tr>
<tr>
<td>90303</td>
<td>20</td>
</tr>
<tr>
<td>90304</td>
<td>35</td>
</tr>
<tr>
<td>90305</td>
<td>45</td>
</tr>
</table>
I tried nested foreach statements and played with sections, but I can't figure out how to loop through it correctly...
The array looks like this:
Array
(
[TM98800G] => Array
(
[zid] => Array
(
[0] => 90001
[1] => 90002
[2] => 90003
[3] => 90004
[4] => 90005
)
[count] => Array
(
[0] => 10
[1] => 10
[2] => 20
[3] => 25
[4] => 15
)
)
[TM76654G] => Array
(
[zid] => Array
(
[0] => 90301
[1] => 90302
[2] => 90303
[3] => 90304
[4] => 90305
)
[count] => Array
(
[0] => 25
[1] => 25
[2] => 20
[3] => 35
[4] => 45
)
)
)

<h5>TM98800G </h5>

<tr>
<td>90002</td>

<tr>
<td>90003</td>
<td>20</td>
</tr>
<tr>
<td>90004</td>
<td>25</td>
</tr>
<tr>
<td>90005</td>
<td>15</td>
</tr>
</table>
<h5>TM76654G</h5>
<table>
<tr>
<td>90301</td>
<td>25</td>
</tr>
<tr>
<td>90302</td>
<td>25</td>
</tr>
<tr>
<td>90303</td>
<td>20</td>
</tr>
<tr>
<td>90304</td>
<td>35</td>
</tr>
<tr>
<td>90305</td>
<td>45</td>
</tr>
</table>

-corrected (fixed </tr> placement)
-added more descriptive comment of strategy
-added more descriptive comment of strategy
foreach ($zarray $k1 => $v1){
echo "<h5>$k1</h5>";
echo "<table>";
$v2 = $v1['zid'];
foreach ($v2 as $k3 => $v3){
echo "<tr>";
echo '<td>' . $v3 . '</td>';
echo '<td>' . $v1['count'][$k3] . '</td>'; // use sibling key [k3] of zid from forloop to index the count subarray
echo "</tr>";
}
echo "</table>";
}
normalized quotes
foreach ($zarray $k1 => $v1){
echo '<h5>' . $k1 . '</h5>';
echo '<table>';
$v2 = $v1['zid'];
foreach ($v2 as $k3 => $v3){

echo '<td>' . $v1['count'][$k3] . '</td>'; // use sibling key [k3] of zid from forloop to index the count subarray

fixed foreach line 1

...and he uses smarty, so he probably is looking a way to do it without raw PHP.
Here is the documentation for the foreach loops, which can be nested (seems that it is what you need): http://www.smarty.net/manual/en/language.function.foreach.php
This might also help: http://www.smarty.net/forums/viewtopic.php?p=6740
The other way of doing it is storing in a string what NerdsOfTech is echoing and assigning it to a smarty variable, but that beats the purpose of smarty.

This solution is only available to members.

try replacing line 7 of my sniplet with:
<td>{$v1.count.$k2}</td>
or
<td>{$v1.count.k2}</td>
see if that does the trick
<td>{$v1.count.$k2}</td>
or
<td>{$v1.count.k2}</td>
see if that does the trick
Also, if you have template security disabled then you could do raw PHP from smarty directly with my previous code:

{php}
foreach ($zarray as $k1 => $v1){
echo '<h5>' . $k1 . '</h5>';
echo '<table>';
echo '<tr>';
$v2 = $v1['zid'];
foreach ($v2 as $k3 => $v3){
echo '<td>' . $v3 . '</td>';
echo '<td>' . $v1['count'][$k3] . '</td>'; // use key of sibling key [k3] from forloop
}
echo "</tr>";
echo "</table>";
}
{/php}
Cool, I didn't know that one could actually use PHP in Smarty templates.
(Sad however, how some people keep using smarty insead of nice 3-layered patterns such as MVC *whistles*)

$zarray is the name I placed on your array; please change this to your array name.
