[SOLVED] another question for everyone who knows what there doing

Reaper0167 · December 31, 2008

i have a html page with a form and a php with a script. in the script i have a if/else statement. could i put javascript in the php script inside the if/else so it would display in a div on the html page after a submit button was clicked?

awpti · December 31, 2008

Yup, just have to use PHP to echo it out first. PHP is server-side, JS is clientside. You can use PHP to spit out javascript which should then be executed by the browser.

RussellReal · December 31, 2008

yes you can..

E.G..

<?

if (whatever == lolol) {

?>

lalalal

</script>

<?

}

else {

?>

OMG LOL!

</script>

<?

}

?>

RussellReal · December 31, 2008

sorryy made a mistake above, but I just modified it to make it work

Reaper0167 · December 31, 2008

okay cool. can the javascript text appear on the html page inside a div?

Sesquipedalian · December 31, 2008

Yeah, but whats the point of doing that?

<?
if (...) {
echo '<div><script>...</script></div>';
} else {
echo '<div><script>...</script></div>';
}
?>

Reaper0167 · December 31, 2008

so the text "lalalal".... i'm looking to place that in div on the html page

Reaper0167 · December 31, 2008

check out this page... mylahstone.com just enter any name and password.

i don't like the separate page it goes to for the error. and i don't want an alert box to pop up... i know how to do all that. i would like the error to appear on the same page.

Reaper0167 · December 31, 2008

ooppsss wait one second til i fix it.... sorry

Reaper0167 · December 31, 2008

ok, check it out...sorry bout that.

http://mylahstone.com/login.php?username=jhbnklm%3B&password=tyiokpl&submit=++Log+in++

\

use method="POST" for your user login form..

Reaper0167 · December 31, 2008

thanks for the heads up on that... i switched it to post... i always put a div with some text on the html page where i would like the error to appear instead of on the new page.

RussellReal · December 31, 2008

i put a random username

and a random password

but it says invalid username lol

Reaper0167 · December 31, 2008

it should because there is no one registered yet.. the error that you got on the new browser window is the one that i am wanting to display on the page that the form is on.

RussellReal · December 31, 2008

ok

you don't need javascript

do this..

<?php
  if (your condition) {
    $message = "1 message";
  }
  else {
    $message = "another message";
  }
?>
<html>
  <head>
  </head>
  <body>
    <div><?php echo $message; ?></div>
  </body>
</html>

Reaper0167 · December 31, 2008

thanks for the help but now when i click on submit it takes me to the php page and that is empty. here is the code.

login.php

<?php
// log in success or failure

if ($count == 1) {
$message = "You are now logged in.";
    
} else {
$message = "This username is not registered. Pleaser register first.";

}

?>

and my div code

index.html

<?php // this page is html not php
<div>
      <div align="center"><?php echo $message; ?></div>
</div>
?>

Reaper0167 · December 31, 2008

so does anyone know how to display this in a div on the original form page? i think i'm going crazy looking all over for this.

RussellReal · December 31, 2008

and my div code

index.html

<?php // this page is html not php
<div>
      <div align="center"><?php echo $message; ?></div>
</div>
?>

get rid of those <?php and ?> tags from around your divs.. and then your problem is solved..

Reaper0167 · December 31, 2008

i just put the php tags in there so the code was easier to read.

ok,,, here is all the code so far. check out the page if you would like.

http://mylahstone.com

the red text is where i'm looking to put the success/error message,, not in a seperate browser window.

// this is the php page with my form
<?php
<html>
<head>

<style>
.error { color: #ff0000; }
</style>
<!-- using javascript to make sure fields are not left empty -->

    <script type="text/javascript" language="javascript">

    function validate(form1)
    {
    var valid = true;

    if (form1.username.value)
    {
        document.getElementById('username_error').innerHTML = '';
    }
    else
    {
        document.getElementById('username_error').innerHTML = 'Please enter a username.';
        valid = false;
    }

    if (form1.password.value)
    {
        document.getElementById('password_error').innerHTML = '';
    }
    else
    {
        document.getElementById('password_error').innerHTML = 'Please enter a password.';
        valid = false;
    }
    return valid;
    }
    </script>
    
<style type="text/css">

// this is the php with the script
<?php

$db_name = "-----------"; // database name
$tbl = "-------------"; // table name

// connects to server and members databse.
mysql_connect("$host", "$dbusername", "$dbpassword") or die("cannot connect");

// username/password changed to variables.

if ($count == "1") {
    echo "Thank you for logging in.";
} else {
    echo "This is not a registered username. Please register before logging in.";
}
?>

oh then do the check @ the top of the php page..

if fail

header("location: index.php?error=".urlencode($message));

then in index.php

put

$_GET['error'] inside the div

Reaper0167 · December 31, 2008

i think we are getting closer.. after clicking the submit button,,, it keeps us on the index page but the error is displayed up top in the url box.

http://mylahstone.com/index.php?error=This+username+is+not+registered.+Pleaser+register+first.

I'll keep playing around with it.

Reaper0167 · January 1, 2009

bump ttt,,,,, anyone?

RussellReal · January 1, 2009

for the div on the page do:

Reaper0167 · January 1, 2009

nothing yet,,,,,i think i already tried putting the div inside a form and setting the form also... but that did not work.... i am out of ideas. i keep thinking it is something in this line of code

<?php
header("location: index.php?error=" . urlencode($message));
?>

Reaper0167 · January 1, 2009

i know he is probably getting tired of me but where is RussellReal when you need him, lol.
