Using an array for $_POST

viion · April 1, 2009

I need to make an array of $post values. I thought something like

$value[$i] = $_POST['$checkboxName[$i]'];

...Would work, by putting it in a for loop. My code is:

$x = 0;
for (; ; ) {

if ($x > "$possible_choice_array_totalx" -1) {

break;

}

$result[$x] = $_POST['$possible_choice_arrayx[$x]'];

echo "$x possible = $possible_choice_arrayx[$x] | $x choicex = $result[$x] <br />";

$x++;

}

Not working, any help on how to get a post array working.

Why not just use foreach to iterate through the $_POST array.

As far as what you are trying to get it, I cannot see. But your for statement is not valid. I would look up at the manual for proper usage of that. Since it seems as though you have multiple check boxes here is an example:

foreach ($_POST['checkboxesname'] as $key => $val) {
    echo "Checkbox: {$key} contains a value of {$val}<br />";
}

try this it should work

for ($x = 0; $x >  ($possible_choice_array_totalx-1) ; $x++ )
{
$result[$x] = $_POST["$possible_choice_arrayx[$x]"];
echo "$x possible = $possible_choice_arrayx[$x] | $x choicex = $result[$x] <br />";
}

Let me know how it goes

Hmm, neither worked. They didn't show a report.

How do I post a PHP tag so it's coloured?

All the check box's are different names. depending on their value. So the Name is exactly same as the value like:

<input name='$v' type='checkbox' value='$v' /> $v

I tried bit snippets and adjusted them accordingly but both do not post anything. When a check box is True.

Post a few checkboxes (the actual html) of your form, so we can see what you are working with.

As for the pretty colors you can use

without the <?php or with the <?php

should work for coloring.

Check box's are pulled from a function known as showChoices();

Which includes this:

// The values for possible_choice_array and users_choice_array have already been determind and so the variables are ready.
$qwert = array_values($possible_choice_array);
$qwert2 = array_values($users_choice_array);
foreach ($qwert as $v) {
if (in_array("$v", $qwert2)) {
	echo "<input name='$v' type='checkbox' value='$v' checked/> $v";
} else {
	echo "<input name='$v' type='checkbox' value='$v' /> $v";
}
}

An example output would be:

<input name="KirinsOsode" value="KirinsOsode" type="checkbox"> KirinsOsode
<input name="Kirins Pole" value="Kirins Pole" type="checkbox"> Kirins Pole

Then when the user hits submit it calls another function called editWishlist();

The code for this is so far:

function editWishlist() {
// Pull all SQL tables, the below values are ready to work.

while ($possiblelistx = mysql_fetch_array($possible_choice_sqlx) ) { 
	// PULL
	$possible_choicex = $possiblelistx[MONSTER_DATABASE_MOBDROP];
	// SPLIT
	$possible_choice_arrayx = explode("|", $possible_choicex);
	// COUNT
	$possible_choice_array_totalx = count($possible_choice_arrayx);


	// For statements pasted/edit here and tested.
	// EG below	
	for ($x = 0; $x >  ($possible_choice_array_totalx-1) ; $x++ )
	{
		$result[$x] = $_POST["$possible_choice_arrayx[$x]"];
		if ($result[$x]=="True") {
			echo "$possible_choice_arrayx[$x] Selcted <br />";
		}
	}
}
}

Ok, well for one, the name has a space in it. That usually is not kosher.

Second you could make it an array of checkboxes by doing this:

foreach ($qwert as $v) {
if (in_array("$v", $qwert2)) {
	echo "<input name='checkboxname[$v]' type='checkbox' value='$v' checked/> $v";
} else {
	echo "<input name='checkboxname[$v]' type='checkbox' value='$v' /> $v";
}
}

Then using this:

foreach ($_POST['checkboxname'] as $key => $val) {
    echo "Checkbox: {$key} contains a value of {$val}<br />";
}

Should give you an idea how to use that to do your tests.

Okay that works =D, the outcome is rather odd though. It's rendering the results 5 times. So an outcome of select 3 box's would come out like this:
