[Creating a register/login script...]

well drace, did you try it after the mysql_query correction? And, is the password encrypted in the table? If so, u need to match encrypted post-value against the stored db-value

[Creating a register/login script...]

Inside you query, ditch the &&, use AND

 

$query = "SELECT * FROM pr0n_members WHERE username='$username' AND password='$password'";

[What's wrong with this code]

No, that's fairly easy - detect based on if the title is present or not in the adress bar:

<?php

if(!empty($_GET['title'])){ // title is present - do search

$dropdown = htmlspecialchars($_GET['title'],ENT_QUOTES);
$sql = mysql_query("SELECT * FROM recipes WHERE title='$title'");

while($row = mysql_fetch_array($sql)){
echo <<<_HTML
  <h4>
   {$row['title']}<br />
   {$row['ingredients']}<br />
   {$row['method']}<br />
  </h4>
_HTML
}
}
else // title is absent or empty - show dropdown
{
echo <<<_HTML
<form action="this.php" method="get">
<select name="title">
_HTML;

$query = mysql_query("SELECT title FROM recipes");

while($dropdown = mysql_fetch_array($query)){
  echo "<option value=\"".$dropdown['title']."\">".$dropdown['title']."</option>";
}

echo <<<_HTML
</select>
<input type="submit" name="Submit" value="Submit" />
_HTML;
}

?>

Should do it...

[What's wrong with this code]

Name the select

 

<select name="title">

 

And add the value

 

echo "<option value=\"".$dropdown['title']."\">".$dropdown['title']."</option>";

 

 

[Stand alone Forums]

You allow too much jumbo to be posted, i was able to change the background color of your page way too easy.

Example: http://www.13thstar.info/forums.php?act=posts&topicid=8

[Problem with showing specific details.]

Look at the colored part,

the variable is just written outside any definition or echo and it misses the mandatory ;

 

 

if ($artist_fn != "") {

$artist_fullname = trim("$artist_fn $artist_ln");

 

//************ error is in here - else - ? ***************

$artist_fullname; } else {

$artist_fullname = trim("$artist_ln");

}

//************************************************

 

 

Look at this
<?php

if ($artist_fn != "") {
$artist_fullname = trim("$artist_fn $artist_ln");
}
else {
$artist_fullname = trim("$artist_ln");
}

if ($date_acq == "0000-00-00") {
$date_acq = "[unknown]";

$display_block .= "<P><strong>$title</strong> on $rec_label,
by $artist_fullname<br>
$my_notes <em>(acquired:$date_acq, format:$format)</em></P>";
}

?>

[Linking Help]

Do you mean how to "read" the id from the adress-bar and how to use it ?

 

Example with mysql:

<?php

if(!empty($_GET['member_id'])){
  $member_id = $_GET['member_id'];
  $sql = mysql_query("SELECT * FROM members_table WHERE id='$member_id'");
  if(mysql_num_rows($sql)==1){
    $col = mysql_fetch_array($sql);
    echo "User ".$col['name']." has ID ".$col['id'];
  }
  else{
    echo "No user found with ID ".$member_id;
  }
}

?>

 

But it boils down to how your existing members page is constructed, but $_GET['whatever'] wil get 'whatever' from the adress bar.

[[SOLVED] Pulldown menu help]

Normally it should work just aswell in a php file as long as you have this outside any php tags.

What's the problem then?

[Headers already sent, but how?]

You cannot have any whitespace, lines or other output to the browser before the php start-tag

 

OK:

------------------------------------------------------------------

<?php

session_start();

 

 

ERROR:

------------------------------------------------------------------

 

<?php

session_start();

 

 

 

Means it's ok to put session_start() 'anyhwhere' as long as no output is done before it.

[Session is not working]

Try to remove session_write_close() - it ends the session, http://no.php.net/manual/en/function.session-write-close.php

[Emailing Signup]

Its all about how you define your message string, look at this:

<?php

$password = "12345";

echo $password; // prints 12345

echo '$password'; // prints $password

echo "$password"; // prints 12345

?>

[adding a .php page on sign up]

Use str_replace() instead of preg_replace()  if you don't need fancy replacing rules

<?php

$username = str_replace(" ", "_", $username);

?>

[why isnt this variable getting in to my query string?]

In your linking part, try this:

<?php

echo '<li><h3>';
echo $upload;

if(isset($upload)){
  echo '<a href="individualarticle.php?f=1&blog_id=' .$blog_id. '">';
}
else{
  echo '<a href="individualarticle.php?f=0&blog_id=' .$blog_id. '">';
}

echo $title .'</a>';

  echo '<img src="pin.gif" />';

[[SOLVED] Another while() problem]

The problem is that you are constantly overwriting the $sql variable while the loop is running

 

Try something like this:

<?php
include("check.php");
include("include.php");
if($_SESSION['auth']) {
$query = mysql_query("SELECT id, title, category, status FROM software");
echo "<table align='center' cellpadding='2' cellspacing='2' width='100%'>
	<tr bgcolor='#1469A2'>
	<td width='50%'><b>Software Title</b></td>
	<td width='20%'><b>Category</b></td>
	<td width='15%'><b>Status</b></td>
	<td width='15%'><b>Check Out?</b></td>
	</tr>";
while ($data = mysql_fetch_array($query)) {

	echo "<tr bgcolor='#003C64'>
		<td width='50%'>".$data['title']."</td>
		<td width='20%'>".$data['category']."</td>

	}
	else {

	}
	echo "</td></tr>";
}
echo "</table>";
if(isset($_POST['checkout'])) {
        $date = date("Y/m/d");
        $username = $_COOKIE['cis_username'];
        $id = $_POST['id'];
        $sql = "UPDATE `software` SET `status` = 'Checked Out', `by` = '$username', `date` = '$date' WHERE `id` = '$id'";

[generate a fixed .htm from a dynamic .php everytime the page is loaded]

Here is part of a newsletter thing i wrote a while ago, i'm sure you can adjust it to your needs.

Read comments

<?php

// prepare to save a html version of news.php
// make sure you already have a blank html page to duplicate from
$source_html_doc = "../newsletter/archive/blank.html";
$today = date(dmY);
$new_blank_html_doc = "../newsletter/archive/news_".$today."html";
copy($source_html_doc, $new_blank_html_doc)or die('Could not copy required file');

// start getting the generated contents of news.php
ob_start();
require("news.php"); // or run php contents here instead
$body_news = ob_get_contents();

// write a html version of it as archive
$html_change = fopen ($new_blank_html_doc, 'w');
fwrite ($html_change, $body_news);
fclose ($html_change);

// END ob_start
ob_end_clean();

?>

[generate a fixed .htm from a dynamic .php everytime the page is loaded]

I think what you might be mistaking about showing a url like that, is that it's mostly due to mod_rewrite. Generating a htm page each time is a waste if it's purpose is to only present the user of a "what seems to be" htm

Dunno if this is what you are looking for, but it checks whether the required one is present and walks throug all - included optional ones

[[SOLVED] how to change @ to _AT_ and # to _SHARP_ etc]

Sorry - a glitch with the array, but you seem to grasp it and that's the point!

[[SOLVED] how to change @ to _AT_ and # to _SHARP_ etc]

I notice from a prev post that you are on php4, here is a str_split function to get my above example running under php4

<?php

function str_split($string)
{
$piece = array();
$length = strlen($string);
for($i=0;$i<$length;$i++) $piece[] = $string{$i};
return $piece;
}

?>

[[SOLVED] how to change @ to _AT_ and # to _SHARP_ etc]

Here is one, note that its php5 dependant due to str_split()

<?php

$string = "kfgak*suh@hd#t";

$invalid = array();
$filtered = array_values(str_replace(array_merge(range(a,z),range(A,Z),range(0,9),array('.')),'',str_split($string)));
foreach(str_split($string) as $char){
  if(in_array($char,$filtered,true)){
    $invalid[] = $char;
  }
}

if(!empty($invalid)){
  $string = str_replace(array("@","#"), array("_AT_","_SHARP_"), $string);
  $string = str_replace(array_values(str_replace(array_merge(range(a,z),range(A,Z),range(0,9),array('-','.','_')),'',str_split($string))),'_ILLEGAL_',$string);
  echo "<p>Following chars was not accepted:</p><ul><li>";
  echo implode($invalid,'</li><li>');
  echo "</li></ul>";
  echo "String was translated to: $string";
}
else{
  echo "No illegal chars found";
}

?>

 

This example prints out:

Following chars was not accepted:

    * *
    * @
    * #

String was translated to: kfgak_ILLEGAL_suh_AT_hd_SHARP_t

 

No regex though...

[[SOLVED] how to strip illegal chars by regex]

Here is a non-regex version:

<?php

$string = "gsjdtb7l,-'%&!";

echo str_replace(array_values(str_replace(array_merge(range(a,z),range(A,Z),range(0,9),array('-','.')),'',str_split($string))),'',$string);

// prints: gsjdtb7l-

?>

 

EDIT* Requires php5 though due to str_split()

[from one # to another]

 

<?php

if(in_array($activity, range(1,6))){
  $activity1 = "New Member";
}

?>
