Question

In my form: I have 8 checkboxes that will save to MySQL as a string/varchar (not an int).

Ex:

• Checkbox 1 = Apple
• Checkbox 2 = Orange
• Checkbox 3 = Mango
• Checkbox 4 = Grape
• Checkbox 5 = Watermelon
• Checkbox 6 = Melon
• Checkbox 7 = Pineapple
• Checkbox 8 = Cherry

Now, I want to output this to 3 different fields with limited number of characters per field.

• Field 1 = Has a limit of 25 Characters
• Field 2 = Has a limit of 30 Characters
• Field 3 = Has an unlimited Characters

If all checkboxes are check and save into MySQL, the output will be:

• FIELD 1: Apple, Orange, Mango (this field can only hold 25 characters, so I have to put the next variable data into FIELD 2).
• FIELD 2: Grape, Watermelon (this field can only hold 25 characters, so I have to put the next variable data into FIELD 3).
• FIELD 3: Melon, Pineapple, and Cherry

I did some research on STRLEN, EXPLODE, etc. and somehow I can’t put this together in PHP.
How could I do it?

Perhaps wordwrap will do the trick? One way of doing it is (not tested):

$string_list = explode("\n", wordwrap($string, 25));
$field1 = array_shift($string_list);
$string = implode(" ",$string_list);

$string_list = explode("\n", wordwrap($string, 30));
$field2 = array_shift($string_list);

$field3 = implode("\n", $string_list);
