Multiple Sellect Box

marque

Hi I'm sure this has been answered many times, but can someone answer it again, i can't figure it out.

The problem is I have a static, multiple select box in a form, when i submit the form I only get the last option the user selected. And I can't print it in a foreach statement.

here's my code:

foreach($PriceRange as $key => $value)
{
echo"$key<br>";
}

this is suposed to print a list of options the user selected, like so:

$100
$200
$300

...

It's just not hapening. 🙁

Can anyone help?

Hi,

for your check box, you should have something like this..

<input type=checkbox name=PriceRange[] value="$100"> Checkbox 1
<input type=checkbox name=PriceRange[] value="$200"> Checkbox 2
<input type=checkbox name=PriceRange[] value="$300"> Checkbox 3
.....

your php code:

foreach($PriceRange as $key => $value) 
{ 
    echo $key."  ".$value."<br>"; 
} 

[code=php]

Hey thanks,

but it's not a check box it's a sellect box

It gives the users a list which they can highlight by holding down ctrl while clicking the option.

Seems to me you are missing a counter.
you could try adding i++ after your echo like this:

$i = 0;
foreach($PriceRange as $key => $value) 
{ 
echo"$value<br>"; 
$i++;
}

or you could Try this:

$Pricerange = array (
    "one" => 1,
    "two" => 2,
    "three" => 3,
    "seventeen" => 17
);

foreach($Pricerange as $key => $value) {
    print "\$Pricerange[$key] => $value.\n";
}

Hope that helps

Hi Marque,

This code will work what you want. Just put the <select> name as array, so it can store multiple value when submit the form.

 
<?
//var_dump($PriceRange);
foreach($PriceRange as $key => $value) {
	echo"<br>KEY:$key >> VAL:$value";
}
?>
<form method=post action="<?=$PHP_SELF?>">
<select name="PriceRange[]" size="5" multiple id="PriceRange2">
<option value="all" selected>List All</option>
<option value="1">$1 to $100</option>
<option value="2">$101 to $200</option>
<option value="3">$201 to $300</option>
<option value="4">$301 to $400</option>
<option value="5">$401 to $500</option>
<option value="6">$501 to $600</option>
<option value="7">$601 to $700</option>
<option value="8">$701 to $800</option>
<option value="9">$801 to $900</option>
<option value="10">$901 to $1000</option>
<option value="11">$1001+</option>
</select>
<input type=submit>
</form>

Thanks

Hi Marque,

This is as same concept if we want to get the multiple value from checkbox.
