[SOLVED] String retrieval help

[psychowolvesbane]

I have a string "Ash?Black?Orange?Red?Yellow?White?" that is created by concatenating multiple results from a checkbox selection on a  form, and I know need to retrieve each value or colour name that occurs before the character "?" and place them into an array, then display all the contents of that array. Can you show me how that can be done?

 

The variable that contains the string is $AvailableColoursStr and the variable $ToFind = "?", and the output should be in a variable called $AvailableColours.

[Ken2k7]

$AvailableColours = explode($ToFind, $AvailableColursStr);

 

That would put them all in the array.

I get this in return:

 

Warning: explode() [function.explode]: Empty delimiter. in /home/www/psychowolvesbane.freehostia.com/details.inc on line 29

 

Line 29:

<p><?php echo "Available Colours: " . $AvailableColours; ?></p>

[Ken2k7]

Think I spelled the variable wrong

 

$AvailableColours = explode($ToFind, $AvailableColoursStr);

[psychowolvesbane]

No I spotted that. It must be something to do with how I am displaying them, does the Explode function use an array as an output method?

Post your current code.

[psychowolvesbane]

$AvailableColoursStr = $record['AvailableColours']; (This is the database record retrieval, works fine as I'm just trying to update an already working page)

 

$AvailableColours = explode($ToFind, $AvailableColoursStr);

 

Output:

 

<p><?php echo "Available Colours: " . $AvailableColours; ?></p>

 

[Ken2k7]

$AvailableColours isn't a string. It's an array. Try:

 

$AvailableColours = implode(", ",explode($ToFind, $AvailableColoursStr));

[psychowolvesbane]

That just added this to the error list:

 

Warning: explode() [function.explode]: Empty delimiter. in /home/www/psychowolvesbane.freehostia.com/details.inc on line 29

 

Warning: implode() [function.implode]: Bad arguments. in /home/www/psychowolvesbane.freehostia.com/details.inc on line 29

 

Same code as you posted.

[Ken2k7]

Ohk, can you post your code.

[psychowolvesbane]

I still think the output should have some method of array extraction, atm it seems only capable of displaying normal values.

 

$AvailableColoursStr = $record['AvailableColours']; (Input)

$AvailableColours = implode(", ",explode($ToFind, $AvailableColoursStr)); (Process)

<p><?php echo "Available Colours: " . $AvailableColours; ?></p> (Output)

[Ken2k7]

I got that part. Can you post more of your code?

 

You sure $ToFind is defined?

[psychowolvesbane]

Well the only parts that concern this are those lines and a single line that defines $toFine with:

 

$tofind = "?";

 

As I mentioned before the rest of the code works already, I'm just adding a new feature to it in a very localized area.

 

Also if you need a reminder:

 

$AvailableColoursStr ="Ash?Black?Orange?Red?Yellow?White?" or something similar depending on what colours were chosen in a separate form.

[trq]

So have you defined $tofind or $ToFind ? They are two different variables.

[psychowolvesbane]

Ah thank you  I didn't think it would affect it like that, it works great now, thanks!

[psychowolvesbane]

However before I finish, is there a way to actually enter each colour into an array for retrieval without posting them all at once? I need to display them in a table with each colour in separate columns in a later part of my website.

[psychowolvesbane]

Anyone?

[Ken2k7]

You could have waited more than 10 minutes. Read the rules.

 

$AvailableColours = explode($toFind, $AvailableColoursStr);
