PHP - Simplest "login" Ever Wont Work

Can someone please help me with an array problem i can not figure out.

I need the array to be numbered from 1 to how ever many fields that are needed in the form and have a mysql field name and the title of the field also in the array.

1, "mysql_field_name", "Title of form field"
2, "", ""

and so on

then the form will be shown based on the array.

I have the following draft code which I am working with.

any suggestions on how i may do this array ?

Code: [Select]
<?php
$options = array(
'1'=> array('fieldtext'=>'option1', 'mysqlfield'=>'option1'),
'2'=> array('fieldtext'=>'option2', 'mysqlfield'=>'option2'),
'3'=> array('fieldtext'=>'option3', 'mysqlfield'=>'option3'),
'4'=> array('fieldtext'=>'option4', 'mysqlfield'=>'option4'),
);


// $options = array(1 => "option1", "option2", "option3", "option4");

// the line above works but i want to include the name of the mysql field as well.

$userid = 1;

?>
<div style="align: center; margin: 12px; font-family:Tahoma;">
<br><br><?php
if ($_POST['Update'] != "Update") { // check if form submitted yet, if not get data from mysql.
$res = db_query("SELECT * FROM `users` WHERE `userid` = '" . $userid . "'");
foreach($options as $key => $value) { $_POST[$key] = mysql_result($res, 0, $value); }
$ok_to_update = "no";
} elseif ($_POST['Update'] == "Update") { // check if form submitted yet, if so get POST data.
// error checking
// foreach($options as $key => $value) {
// $_POST[$i] = "";
// }
$ok_to_update = "yes";
}

if ($_POST['Update'] == "Update" && $ok_to_update == "yes") {
// $res = db_query("INSERT INTO `users` () VALUES ()"); // add user details to database.
?><p><br><br><br>Thank you for updating</p><?php
} else {
?><form name="form1" method="post" action="">
<?php foreach($options as $key => $value) {
?><p><?php echo($value); ?>:&nbsp;<input type="text" name="<?php echo($key); ?>" value="<?php echo($_POST[$key]);?>"></p>
<?php } ?>
<input name="Update" type="submit" value="Update">
</form>
<?php } ?>
</div>

Hi,

bit stuck on how to find and replace "<" and ">" with "&lt;" and  "&gt;". I basically have a database record that outputs to screen and I need the code in the <code> tags to be rendered to the screen. I therefore need it to go through the whole array variable from the db and change the symbols just inside the code tags. Please be aware that the code tags might happen more than once

here's an example below

Code: [Select]
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
<h1>hello</h1>
</code>
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
<h1>hello</h1>
</code>

the desired output would be:

<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
&lt;h1&gt;hello&lt;/h1
</code>
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
&lt;h1&gt;hello&lt;/h1
</code>

help on this would be great

Cheers

Rob

Ok soon i can't take this any more, there IS nothing wrong with this code! I've checked it, i have double checked it, tripple checked and then checked it again bit for bit and I can't find anything that suggest i should get these messages:

Notice: Undefined index: birth_month in [php file location] on line 30

Notice: Undefined index: birth_day in [php file location] on line 31

Notice: Undefined index: birth_year in [php file location] on line 32

Notice: Undefined index: iagree in [php file location] on line 33

I have one file with the HTML form named "register.php" and another file with the PHP code to process the form named "class.register.php". I don't know if it matters but i have to solve this to be able to move on with my website so i'll try to bring you all the facts and info i have..

Here is the HTML file/code (register.php):
Code: [Select]
<?php
session_start();

if(isset($_POST['register']))
{
  include_once('classes/class.register.php');

  $register = new Register();

  if($register->process())
    echo "Successfully Signed Up!";
  else
    $register->show_errors();
}

$token = $_SESSION['token'] = md5(uniqid(mt_rand(),true));
?>

I really need help with this.. So if you have 10 min or so to scroll through my code and see if you can see any direct faults i would really appreciate it! Cause I can't find anything wrong with it!

Note: I tried to solve it by changing the top part of the PHP code from:
$this->birth_month  = $this->filter($_POST['birth_month']);

$this->birth_day    = $this->filter($_POST['birth_day']);

$this->birth_year   = $this->filter($_POST['birth_year']);

$this->iagree       = $this->filter($_POST['iagree']);

To:
$this->birth_month  = $this->filter($_POST['birth_month'] = "");

$this->birth_day    = $this->filter($_POST['birth_day'] = "");

$this->birth_year   = $this->filter($_POST['birth_year'] = "");

$this->iagree       = $this->filter($_POST['iagree'] = "");

That did take away the messages but instead whenever i for example chose a date in the dropdown menu it would always return false..

Hi guys

I am a newbie with PHP and I have been trying to solve this problem for 3 days..

Ive set up a booking form on my website to be sent directly to my email once the client clicked on the send button..
The problem I am having while checking these pages on wamp is that the booking form is ok but when I click on the send button the following message error appears
"Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\wamp\www\fluffy_paws\booking_form2.php on line 27"

When I check online I have this message "500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed."

Are my codes wrong???

My webhosting is Blacknight.com , Im on Windows Vista, my internet is a dongle with O2 ireland

Thanks for your help!

Hi guys

I'm struggling a bit, I need to replace a word that occurs multiple times in text with an array("up","down","forward","backwards") of words.


$find = "left";
$replace = array("up","down","forward","backwards");
$text = "left left left left";

echo str_replace($find,$replace,$text);


The Output is: array array array array

Did try this with a foreach statement as well, but no luck. Is there a better way of doing this? 

Thanks
