FOR a problem with insertions

rulinus

Hi, hope someone can help me 😃
I have a dinamicaly created insert form, where the number of fields are created by a user-declared number. I used a FOR loop to create them:

 for($i = 1; $i <= $jug; $i++){
          echo "<font size=2 face=Tahoma>$i. Numero de jugador: 
          <input name='numerox$i' type='text' id='numerox$i' size='3' maxlength='2'>
          Nombre: 
          <input name='name$i' type='text' id='name$i' size='15'>
          Posicion: 
          <input name='pos$i' type='text' id='pos$i' size='5' maxlength='20'>
          </font><br>
          <hr align='center' width='150'>";
		  }

I still don't know if identifying the name of of the input fields with name='name$i' was a good idea, but anyway. The real problem comes later on, when the form is submitted. I want the data inserted in a mysql table, but i also want the fields validated (simple present or absence of data). I thought of placing the same FOR loop, but the problem comes when identifying the variables. I tried something like this:

if($equipo){ #other variable i need present
	if($jug){ #other variable i need present
		for($i = 1; $i <= $jug; $i++){
		if($numerox["??"]){ #here's the problem!!!!
 Insert the data in mysql
        echo "$i. Data inserted<br>";}
		else { echo "$i. you missed a field!<br>";}
		}
		}}

Can any one help!!!
thanks in advance

You want variable variables I think, which are as confusing as hell. Let me dig out some code 🙂

Right, the form will be fine. Make sure you have a hidden field with the number of fields though, so the final script knows what its doing!

Then, read up on variable variables 😃

I did exactly the same kind of script, and on the last page this is what the loop goes like:

for($i = 1; $i < $number2; $i++){
$b=${'form_map'.$i};

}

Is what happens, in the first looop it makes a variable called $b have the data of a variable $form_map$i (Or $form_map1 in the loop) thus giving it the data from the form with variables of $form_map1. And $number2 would be the number of variables in the form, kinda thing.

That make sense? Like I say, they get quite confuddling.

So, you should be able to play about with it and make it do what you want.

thanks hermand, you've been very helpful.
Now there's something bizzare going on, the
for($i = 1; $i <= $jug; $i++){
$b=${'name'.$i};
}
works fine... just what i was looking for, but as a test i echoed the $b array as $b["name"] and it seems to do the trick except for the small detail that it only displays the very first letter of the tex, or the fist number of the text.
eg. if $name1 was "hermand", when printed i only see "h"

It's dazzling 😕

hermand

You should be able to just

echo $b;

and it should echo the text inputted to the form?
