problem with form ...

[nomad9]

Hi all,

i've got 2 question :

1. My form contain a lot of field and i want that each time a form is not filled correctly /or the user want to go to the preview page, the form still got the information that the user filled before ... i know that i can do it with session variable but it's mean a lot of variable .... is session variable is the best way ... or the only way ???

2. Inside my form, i've got a section that contain 15 textfield. With this textfield, i've got to make a dropdown list ... so each textfield filled will be an option in html :

<select name="analyseOne">
<option value="1">textfield1</option>
<option value="2">textfield2</option>
<option value="3">textfield3</option>
...
</select>

but the problem is that i don't know how much textfield the user will filled (the user can filled textfield as much as he want).

So How can i detect how much textfield the user have filled.

Thanx alot,

Steve

yes you want to use a session to store the form across pages:

this is very straight forward

just like normal you write:

    # form.php
    <form action="submit.php" method="post">
    <input type="text" name="field1" />
    <input type="text" name="field2" />

which willl show up when submitted as

    # submit.php
    $_POST['field1'];
    $_POST['field2'];

ok: now to save your whole form in the session you do this

    # submit.php
    if ( $error_in_form ) {
        /// store the form in a session : simple now as its all one variable
        $_SESSION['form'] = $_POST;
        /// return to the form page
        header('Location: form.php');
    }

and rewrite form.php to look for a possible session form.

    # form.php
    <input type="text"
           name="form[field1]"
           value="<?php echo $_SESSION['form']['field1'] ?>">

<input type="text"
       name="form[field2]"
       value="<?php echo $_SESSION['form']['field2'] ?>">

im assuming you have several textareas
and one pulldown...

the pulldown chooses which textarea you want to look at

basicallly you want the [man]strlen/man function to see how much is in a textarea....

$which_text_area = $_POST['analyseOne'];

$text_area_value = $_POST[$which_text_area];

$characters_in_text_area = strlen($text_area_value);

its also possible to have javascript check on the browser before the form i submitted...
