Remember Dropdown Selection

[realph]

Does anyone know of some PHP to remember a form’s dropdown selection on submit?

At the moment I’m using this to remember a selection:


>£100,000

But when you have 10+ options it can get a bit much, is there a simpler way of doing this?

There is no real need to post this twice, albeit with one word changed in the topic from PHP to JavaScript

You could use an array and a foreach statement to save yourself a lot of time

e.g.

$arOptions = array('100', '250', '500', '1000');



foreach ($arOptions as $strOption){

echo '


if ($strOption == $_GET) echo ' selected ';



echo '';



}

Sorry, I wasn’t sure what the topic fell underneath. Is there a way of making all dropdowns remember their selection on submit without repeating that ^.

If you don’t want to clutter the URL:

Set cookie on submit script
Read cookie on new page
Use similar code to Mark’s only you just already have a variable set from the Cookie read, you don’t need to $_GET it.

I’ve found some script (below) which is working for one of the Select Lists (MinPrice). I also need to target the second Select List (MaxPrice), how would I do that?

Just to look at your original code – you can use a shorthand if/else like this…

>£100,000

and the second part – remember to close your first option tag – personally I like to build a var and echo it. You can also use number_format to set how you want your number to float.

$arOptions = array('100', '250', '500', '1000');



foreach ($arOptions as $value){



$e =  "


$e .= ($value == $_GET) ? " selected " : "";



$e .= ">£" . number_format($value, 2, '.', ''); . "";



echo $e;

}

The array works perfectly for one part of the form (Buying), but when you switch the radio button to Renting it calls its JavaScript and pulls its select options from that. I can’t seem to work out a way to use that array in the JavaScript (below):


document.SearchForm.MaxPrice.options[0]=new Option ("Price (Max)","9999999");
document.SearchForm.MaxPrice.options[1]=new Option("u00A3250","250");
document.SearchForm.MaxPrice.options[2]=new Option("u00A3500","500");
document.SearchForm.MaxPrice.options[3]=new Option("u00A3600","600");
