PHP - Re-display form data, including multi checkboxes

[BowlerBob]

Hi

This is probably not the first query on this topic.
If there is already a solution here, please direct me.

I have created a Form that includes name, company, email, etc., but also some topics the user is interested in.
These are in several Select boxes; there is also a multi-choice Checkbox.

The Form is displayed on one page, filled in, then Submitted.
It is Actioned on another page which picks up the $_POSTed data.
At the moment I only Validate the email address.
If there is an Error, the page is redisplayed with submitted data and choices.

My problem is how to fill the Checkbox part from it's $_POST['xxxxxx'] array.
I want to use PHP ONLY (no JavaScript, Perl, etc.)

Hoping someone will be able to solve this and include an example, or direct me to any (simple) solution already on the 'Net


best regards

Bob Sharp

You can preset checkboxes to show as checked with

<input type="checkbox" name="vehicle" value="Bike" [COLOR=red]checked="checked"[/color]/>

Sorry, but I am asking how to re-display all the fields fields with the entries made by the User.

cheers

That's going to depend a bit on how you have your checkboxes set up. But you'll have to check what is submitted in your POST variable by your checkboxes as only the checked options will be sent.

For instance if you have your checkboxes set up as an array you can do something like the following:

<input type="checkbox" name="opts[0]" value="Alpha" <?PHP if(isset($_POST['opts'][0])){ echo "checked=checked"; } ?>>
<input type="checkbox" name="opts[1]" value="Beta" <?PHP if(isset($_POST['opts'][1])){ echo "checked=checked"; } ?>>
<input type="checkbox" name="opts[2]" value="Gamma" <?PHP if(isset($_POST['opts'][2])){ echo "checked=checked"; } ?>>
<input type="checkbox" name="opts[3]" value="Delta" <?PHP if(isset($_POST['opts'][3])){ echo "checked=checked"; } ?>>

That was GREAT ! thanks.

Thought the <SELECT> <OPTION script would be easier (!)

You are either missing a closing parenthesis or have one too many. Either way there's a lone ( that has no closing counterpart.

if [COLOR=black yellow]([/color][COLOR=gray green]([/color]!isset[COLOR=gray blue]([/color]$_POST['qTurnover'][COLOR=gray blue])[/color] && [COLOR=black red]([/color]$_POST['qTurnover']==$a_tOval[$val][COLOR=black red])[/color][COLOR=gray green])[/color][COLOR=black yellow]_[/color]
/*No closing brace to match up*/

Thanks for spotting that.
I don't have a PHP editor, which would you recommend ?

Now the code does not seem to be working.
Any idea why ?

cheers

 

[vacunita]

For Editors, I like Notepad++. Its got syntax highlighting.

I also use PHP Developer though that one is not free.
As for why its not working, its because your conditionals can never be both true.

if ((!isset($_POST['qTurnover']) && ($_POST['qTurnover']==$a_tOval[$val])))

Your checking first if $_POST['qTurnover'] is not set by checking if its different to isset(). !isset()

However you can't want it to be not set, and then check if it has a value. Instead yo want it to be there so you can check for a value.

Remove the ! from your isset conditional, and it should work

if ((isset($_POST['qTurnover']) && ($_POST['qTurnover']==$a_tOval[$val])))
