Form with one-to-many fields ?

egiceme

Hello,
I need to have a form: links_size, links_name, links_link.
The problem is, that it could be sometimes one, sometimes more. Like:

1: links_size, links_name, links_link

2:links_size, links_name, links_link
links_size, links_name, links_link

3:links_size, links_name, links_link
links_size, links_name, links_link
links_size, links_name, links_link

4: ...

... to many

How to make a form to work? To make a form for one, get values, send to MySQL table and load same page again.?
Ore somehow to make a form to ask first how many links I want to enter and then it make's me a new form with a many links as I wanted?

Please help

Well, the easiest way is to do what you mentioned last...

Have a form that asks how many...use that value inside a while loop

<form stuff>
while($count < $howmany){
echo "<form field stuff>"
count++;
}
<submit button>
</form>

I didnt feel writing all the specific stuff but you should be able to figure it out.

Thanks, I got an idea. But I don't know how to: echo form fields?
thats syntaks for PHP to show form fields with echo comand?

I have 3 fields (text): links_size, links_name, links_link

  thaks in advance

... and how to get values links_size1, links_name1, links_link1
for second: links_size2, ...becouse I will need to store values to MySQl database?

werkkrew

its the same as usual except yoyu have to put a \ in front og any quotes

echo "<form method=\"post\" action=\"process.php\">";

etc

egiceme

ok, so if I have links_size1, links_name1, links_link1 so can simple echo it a form and get values, but if I have 5 or 22 of them?
So I need to use a counter and use an array?
If any example or guide, will be very usefull.
Thaks

Watch my syntax here but it will be something like this

Basic form to get how many:

<form name="howmany" method="post" action="process.php">               

<input name="links" type="text" id="howmany" value="">          

<input type="submit" name="Submit" value="Proceed">

This will be basically what "process.php" will be:

<?php
$howmany = $_POST['howmany'];
$content = "<input name=\"links_size\" type=\"text\" id=\"links_size[$i]\" value=\"\">    

<input name=\"links_name\" type=\"text\" id=\"links_name[$i]\" value=\"\">     

<input name=\"links_links\" type=\"text\" id=\"links_links[$i]\" value=\"\"> ";                     

echo "<form name=\"pro\" method=\"post\" action=\"success.php\">";
$i=1;
while($i < $howmany){
    print $content;
    $i++;
}
echo "<input type=\"hidden\" name=\"howmany\" value=\"$howmany\">";
echo "<input type=\"submit\" name=\"submit\" value=\"proceed\">";

This is basically what success.php will be

$howmany = $_POST['howmany'];
$i=1;
while($i < $howmany){
   $links_size=$_POST['links_size[$i]'];
   $links_name=$_POST['links_name[$i]'];
   $links_links=$_POST['links_links[$i]'];
   //DO WHATEVER YOU NEED TO DO WITH THEM HERE
}
//PUT SOME SORT OF NOTIFICATION OF SUCCESSFUL OR FAILED OPERATION HERE

Im not sure how much you know about arrays but these scripts make basic use of arrays....

Of course you will want to use tables and CSS to make this all look nice, but for all intents and purposes this will work.

Remember to check my syntax, I didnt really look over it
