looping through form values

[maxsslade]

Hey,

I have a problem with forms.

I am allowing a user to input how many text boxes they need to enter information. e.g. if a user says they need 6 text boxes, the form displays the 6 six text boxes etc.

The problem I have is reading the values once they are posted to the processing page because the text box names are generated from a loop.

e.g.

text1
text2
text3 ... etc

if i want to read the values on the next page i tried using this code:

while ($i < $the_number_of_boxes){
echo text$i
}

(where $i is the number of times it has been looped)

is there a simple way round this problem?? Thanks for anybody that reads or replies to this post.

Use an array instead of fussing with distinct names. This article discusses SELECT boxes, but the concept is the same for all HTML elements:

To answer your question:

Use this code:

for ($i=1; $i<=$the_number_of_boxes; $i++) {
	$var = "text$i"; 
	echo $$var; 
}
