[SOLVED] Variable inside a $_POST

[Roy Barten]

I made a application where you can store hardware information etc. But i want different types of properties for every kind of hardware. So a laptop has the properties:

 

memory

Processor

etc.

 

and a mobile phone knows other property's like:

 

Camera yes/no

etc.

 

I have to fill in this properties into a variable number of textfields. This information must be stored in a database. But because i have a variable number of textfields the names of the textfields are always different. Into the next page i have to open this information with a post, but how do i call this textfields? Can i place a variable into a $_POST? Like this $_POST[$name]?

Yes, you can. Just like with all other arrays.

Of course, but you'll likely not need to. Just name your text fields as array elements. eg;

 

<input type="text" name="property[]">
<input type="text" name="property[]">
<input type="text" name="property[]">

 

Then, on the recieving page they will be in the array $_POST['property']. You can then loop through this array.

Oke, i've tried something but it does not work, so i have create 2 testfiles with the following code:

 

test.php

<?

$naam = "txttest";

?>

 

<form id="form1" name="form1" method="post" action="uitkomst.php">

  <label>

  <input type="text" name= "<? $naam ?>" />

  </label>

  <label>

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

  </label>

</form>

 

and uitkomst.php

 

<?

$naam = "txttest";

 

echo $_POST[$naam];

 

?>

 

This is only a testfile but the weppage does not echo anything, so something is wrong but what? ???

The only thing I can see wrong there is your using short php tags.

[Roy Barten]

yes, but this is not the problem, I always use short php tags, but the page does not show anything. Maybe a syntax error somewhere? I can't see it!

[trq]

This line...

 

<input type="text" name= "<? $naam ?>" />

 

should be....

 

<input type="text" name="<? $naam ?>" />

 

to make it valid html. Otherwise, I don't see a problem.

 

I think however youv'e missed the point of my last few replies. Firstly, short tags shouldn't be used, there not portable. And secondly, if your creating a variable amount of text inputs your better off naming them using arrays in the first place.

[Roy Barten]

I will try something with those array's. Thank's for you're help!

How about echoing a variable?

 

<input type="text" name="<? echo $naam ?>" />

<input type="text" name="<? echo $naam ?>" />

 

Oh yeah. Indeed. I don't use short tags so didn't even notice.

 

<input type="text" name="<?= $naam ?>" />
