problem populating form input

wikstov

Hello there,

Does this problem sound familiar to any of you?

I have created a form which submits to itself in order to validate the input fields.

Validation works fine, no problem there.
Unfortunately, when the fields that are filled out are reloaded into the browser (<input value=<? print $_POST['variable'] ?>), for some reason only the first word of the string is displayed.

Crazy if you ask me.

Anyone able to help me out? Greatly appreciate it.

Thanks a lot, and best wishes for 2005

you have to do <input value="<?PHP echo htmlspecialchars($var)?>">, since the string you try to put in may contain white space and (")

thats exactly what hes doing, and exactly where the problem is coming from.

wikstov-
you need to use htmlspecialchars() like suggested by dewen
you may also need to use stripslashes()

thanks a lot guys, I finally got it working allright

but now i'm facing a new question:

so i have a form on a page which submits to the page itself for validation

if validation fails, the page is redisplayed indicating where the user made a mistake and how he can correct it

if validation succeeds, however, i want the data to be submitted to another page, which inserts them into a database

how do i handle this? i can do it using session variables, but that doesn't seem the neatest way to do it; including them into the header as 'get' variables is not exactly an option either.

actually, i think i want the data to become available as 'post' variables; but is that at all possible? (e.g. by including a new form which automatically submits to the processing page?)

thanks a lot for your replies, i appreciate it a lot

The way I handle it is like separate the logic from page(form). So it's one php(logic) file + two template(form) file:

in the php file, I do:

<?PHP

// logic 1

// logic 2

// if (logic 1) include template 1

/ if (logic 2) include template 2

wikstov

thanks for your quick reply

i'm planning on using templates, but, as i'm still a newbie, i intended to leave that for later ;-)

what does a template file that only has processing logic in it and does not need to be displayed look like? and how do you handle it? i imagine show -> $template is not the way to go here..

but then again, i'm such a noob that i'm perhaps just talking crap here :-)

pls help me out, thanks a lot

dewen

it's not really a template engine kind of think, that will be too complicate for me. Make it simple here's a sample:

file 1 with logic index.php

<?PHP

if ($_POST['SubmitA']){
// logic of validation puts here
....

if (OK){
// insert to database
require_once('indexA.tpl')
}else{
require_once('indexB.tpl')
}

file 2 with form A indexA.tpl show success msg

file 2 with form B indexB.tpl show failed msg, redisplay the input form

hope it make sense
