Arrays in FORMS

[mclarko]

I am using this code to return an array of values to a PHP script:

$f is just a counter BTW.

<tr>
<td bgcolor=\"#CCFFCC\">
<input type="checkbox"
name="field<?=$f;?>[]"
value=" a value">
</td>
<td bgcolor=\"#CCFFCC\">
<input type="checkbox"
name="field<?=$f;?>[]"

value=" a n other value">
</td>
<td bgcolor=\"#CCFFCC\">
<input type="checkbox"
name="field<?=$f;?>[]"
value="DESC">
</td>
<td bgcolor=\"#CCFFCC\">

<input type="checkbox" 
name="field<?=$f;?>[]" 
value="  a value">

</td>
<td bgcolor=\"#CCFFCC\">
<input type="checkbox"
name="field<?=$f;?>[]"
value="DESC">
</td>
</tr>

My problem is that if a checkbox is not checked, then it does not register as a NULL value in an array element. E.g. Suppose you checked the first and last checkbox. This would return an array of just two elements and not the five I would have expected. Is there a way to insist on the array returning 5 values even if not all boxes are checked (NULL values)?

Cheers!

Hoi,

You can call your checkboxnames in an array.

<input type=checkbox name="chk[1]" value=1>
<input type=checkbox name="chk[2]" value=1>
....

After the submit you can walk through your array with a loop.

for($i=1;$i < 2 /MyLastCheckBoxElement/;$i++){
if(isset($chk[$i] && $chk[$i] == 1){
// Someone checked checkbox nr $i
// Some action
switch($i) {

}
}
else {
// Nobody wanted my checkbox nr $i 😉
}
}
