I don't know under what category to classify this question.

I have say 17 variables in a HTML page, now they all start with "ans" and have the format "ans1", "ans2", "ans3"....

I want to read these variables (and perform certain operations) one by one in a single while loop. How can it be done? I have tried various methods but nothing seems to be working.

I want something like $ans$c where c is incremented.

Thx.

Can't you just use an array? $ans[1], $ans[2], etc. That way you could substitute the number for $c.

**Gimlin** · Aug 10th, 2002, 06:26 AM

make the variable names

myvariable[1]= blah
myvariable[2]= blah blah

etc...

Then you can loop it like an array

for ($x=1; $x<=17; $x++){

print ($myvariable[$x]);

}

I didn't know we could use arrays in HTML. I'm using this vars to get info from an HTML page. For eg,

Code:

<html>
<form>
<h2><b>Would you like to : </b></h2>
1. Do embroidery work.<br>
<input type="radio" name=ans1 value="Yes">
Yes
<input type="radio" name="ans1" value="No">
No
<input type="radio" name="ans1" value="Not Sure">
Not Sure
<br><br>
2. Play with the children.<br>
<input type="radio" name=ans2 value="Yes">
Yes
<input type="radio" name="ans2" value="No">
No
<input type="radio" name="ans2" value="Not Sure">
Not Sure
<br><br>

Now I have 17 such radio buttons. I want to read what value has been inputted by the user for each and every one of the buttons. Get me?

Ok try

PHP Code:




for ($x=1; $x<=17; $x++){



print ($_REQUEST["ans$x"]);



}

well you could do something like this. and then you could call it like what gimlin had

Code:

<html>
<form>
<h2><b>Would you like to : </b></h2>
1. Do embroidery work.<br>
<input type="radio" name=ans[] value="Yes">
Yes
<input type="radio" name="ans[]" value="No">
No
<input type="radio" name="ans[]" value="Not Sure">
Not Sure
<br><br>
2. Play with the children.<br>
<input type="radio" name=ans[] value="Yes">
Yes
<input type="radio" name="ans[]" value="No">
No
<input type="radio" name="ans[]" value="Not Sure">
Not Sure
<br><br>

or you can try this

PHP Code:


while (list ($key, $value) = each ($_POST['ans'])){

  echo "Answer #".$key." =". $value ."<br>";

}

something like that.

try

PHP Code:


for ($x=1; $x<=17; $x++){



print ($_REQUEST["ans"][$x]);



}

**da_silvy** · Aug 17th, 2002, 11:58 PM

or maybe?

PHP Code:


$var = "ans".$x;

print ($_REQUEST[$var]);

I'm not entirely sure what you are trying to achieve

**mralston** · Aug 19th, 2002, 02:20 PM

I believe that $_REQUEST[] won't work in earlier PHP versions.

As long as you put [] after the names of your <input > which share the same name (like scoutt suggested), then PHP will will create an array with that name. You can then use a for() loop to run through the array,whether you use the new $_REQUEST[] collection or not.

He wants a form with, for example 4 inputs ans1 ans2 ans3 ans4. He do whatever with them, using a loop.

I dont know why mine didnt work, I tested it myself.
