Question

I have an array of select drop downs:

<select name="ultimate[<?php echo $theme['id']; ?>]">
    <option value="0">0</option>
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
    <option value="4">4</option>
    <option value="5">5</option>
    <option value="6">6</option>
    <option value="7">7</option>
    <option value="8">8</option>
    <option value="9">9</option>
</select>

<select name="ultimate[<?php echo $theme['id']; ?>]">
    <option value="0">0</option>
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
    <option value="4">4</option>
    <option value="5">5</option>
    <option value="6">6</option>
    <option value="7">7</option>
    <option value="8">8</option>
    <option value="9">9</option>
</select>
......
......
......

When I print these results with:

print_r($_POST);

I get this returned:

[ultimate] => Array ( [1] => 3 [2] => 0 [3] => 0 [4] => 3 [5] => 0 [6] => 0 [7] => 0 [8] => 2 [9] => 0 [10] => 0 [11] => 0 [12] => 0 [13] => 0 [14] => 0 [15] => 0 [16] => 0 [17] => 0 [18] => 0 [19] => 0 [20] => 0 [21] => 0 [22] => 0 [23] => 0 [24] => 0 [25] => 0 [26] => 0 [27] => 0 [28] => 0 [29] => 0 [30] => 0 [31] => 0 [32] => 0 [33] => 0 [34] => 0 [35] => 0 [36] => 0 [37] => 0 )

How would I go about only getting the values of each id that are greater than 0?

Answer 1

this will probably do what do you want

foreach ($ultimate as $key => $var)
{
    if ($var > 0) echo $key.":".$var;
}
