    Calling Php For Authentication

    in PHP Coding Help

    Posted · Edited by White_Lily

    Here is some simple form and validation:

     

    <html>
<head>

</head>
<body>

<?php

//Variables holding the post values
$submit = $_POST["submit"];
$username = mysql_real_escape_string($_POST["username"]);
$password = mysql_real_escape_string($_POST["password"]);

//Runs this if the form was submitted
if($submit){

//checks if the form was empty or not
if(!$username && !$password){
 $msg = "The form was submitted empty.";
}else{

 //checks to make sure a username was entered
 if(!$username){
 $msg .= "Please enter a username.";
 }else{

 //checks to make sure a password was entered
 if(!$password){
 $msg .= "Please enter a password.";
 }else{
 $query = mysql_query("SELECT * FROM members");//Queries the database
 $num = mysql_num_rows($query);//Collects the rows (if any)
 $row = mysql_fetch_assoc($query);//a variable to grab rows with

 //checks if there are any registered members
 if($num == 0){
 $msg .= "There are no members in the database, register first.";
 }else{
 //if there are members this checks the entered username against those in the database
 if($row["username"] != $username){
	 $msg .= "The username does not match any registered members.";
 }else{
	 //if there are members this checks the entered password against those in the database
	 if($row["password"] != $password){
	 $msg .= "The password does not match any registered members.";
	 }else{

	 //if everything succeeds then the sessions will start
	 session_start();
	 $_SESSION["username"] = $username;
	 $_SESSION["password"] = $password;

	 //re-directs the user to the home page.
	 header("Location: index.php");
	 }
 }
 }
 }
 }
}
echo $msg;
}

?>

<form action="" method="POST">
<label>Username:</label>
<input type="text" name="username" />
<label>Password:</label>
<input type="password" name="password" />
<input type="submit" name="submit" value="Login" />
</form>
</body>
</html>

     

    Remember: if the user has logged in you need to carry over the sessions to every single page on the website,

     

    this is done at the very top of the source code (before the doctype):

     

    <?php
session_start();
$username = $_SESSION["username"];
$password = $_SESSION["password"];
?>

    Beginner In Php Need Help With A Music Playlist App

    As for the directory being specified, you have done it slightly wrong - you are using xampp, this means that htdocs (to a browser) doesnt technically exist and is replaced with "http://localhost/siteName" to prove this, echo this out:

     

    $filename = $_SERVER["DOCUMENT_ROOT"];

echo $filename;

     

    This means this line:

     

    $directory = 'C:\Users\test\Desktop\Main\xampp\htdocs\mp3';

     

    Should be:

     

    $directory = $_SERVER["DOCUMENT_ROOT"]."/mp3/";

    Take A Look At This Query Real Quick

    If the table is being found in the database try echoing the rows:

     

    $num = mysql_num_rows($issues);

echo $num;

     

    If it echos nothing (not even a 0) then your query is probably the problem, if it echos '0' then its saying you have no entries, anything higher and the problem is elsewhere.

    How To Manage Database Entries?

    in Application Design

    Posted

    Your not out of line - once ive finished developing it and its fully pre-live checked and post-live checked i will post a link :)

     

    A CMS should be capable of development throughout its life-time, this means that you should be about to take away features and add features depending on your sites needs. This is the one reason why i hate pre-built CMS's such as WordPress, and Joomla. Very difficult to customise those. (sets my teeth on edge just mentioning them >_<)

    Coding Problem For Navigation

    in PHP Coding Help

    Posted

    Hi,

     

    I tried writing some code for my navigation menu to make it easier on my part (with creating the site etc).

     

    I have written this so far:

     

    
<?php

$nav = select("*", "navigation", NULL, NULL, NULL);
$num = mysql_num_rows($nav);
$get = mysql_fetch_assoc($nav);
$filename = file_exists($_SERVER["DOCUMENT_ROOT"]."forum/".$get["file_path"]);

if($num > 0){
while($get = mysql_fetch_assoc($nav)){
if($filename){

$path = $GLOBALS["siteUrl"].$get["file_path"];



echo '<li><a href="'.$path.'">'.$get["page_name"].'</a></li>';
}
}
}else{
echo "<li>Could not find a navigation menu.</li>";
}

?>

     

    Problem is, even though there is an entry in the database (to a page that DOES exist) nothing shows in the navigation area, can't think why.

     

    Any help would be appreciated.

    Uploading Picture Problem

    in PHP Coding Help

    Posted · Edited by White_Lily

    could check to see if the field is empty?

     

    The HTML:

     

    <html>
<form action="" method="POST" enctype="multipart/form-data">
<label>File Upload</label><input type="file" name="file" />
<input type="submit" name="submit" value="Upload" />
</form>
</html>

     

    The PHP:

     

    <?php
if(!$_POST["file"]){
echo "No file selected.";
}else{

//processing code

}
?>
