PHP - N00b Here! Undefined Variables Error
Hi Guys,
Real PHP newbie here, and slowly getting to grips with it (I did say slowly, right!). Basically, I've created this register page. It's supposed to ask the user for their username, password, password verificiation, email address and then finally to ask the user to select from a tick list of interests (populated via the DB). Here's my code: <? include('includes/config.php'); $is_error = 0; if ($_POST['task'] == 'singup_do') { $signup_username = $_POST['user_username']; $signup_password = $_POST['user_password']; $signup_pwd_again = $_POST['user_password_again']; $signup_email = $_POST['user_email_address']; $signup_interest = $_POST['signup_interest']; if ($signup_username == ''){ $is_error = 1; $signup_username_msg = 'The username cannot be left blank'; } if ($signup_password == ''){ $is_error = 1; $signup_password_msg = 'Password field cannot be left blank'; } if ($signup_pwd_again == ''){ $is_error = 1; $signup_pwd_again_msg = 'Password again field cannot be left blank'; } if ($signup_email == ''){ $is_error = 1; $signup_email_msg = 'Email cannot be left blank'; } if ($signup_email != '' && !validateEmailAddress($signup_email)) { $is_error = 1; $signup_email_msg = 'Incorrect E-mail address'; } if (!is_array($signup_interest) || count($signup_interest)==0){ $is_error = 1; $signup_interest_msg = 'Please select atleast one interest'; } //EMAIL ADDRESS VALIDATION if ($signup_password!='' && $signup_pwd_again!='' && $signup_password != $signup_pwd_again) { $is_error = 1; $error_msg = 'Passwords don\'t match'; } //USERNAME DUPLICATION VALIDATION if (!$is_error && $signup_username!='' && !checkUsername($signup_username)) { $is_error = 1; $signup_username_msg = 'Username already taken, please enter another'; } if (!$is_error) { $signup_interest_ids = ( is_array($signup_interest) ? implode(',', $signup_interest) : '' ); $users_insert = "INSERT INTO users SET user_id='', user_username = '{$signup_username}' , user_password='{$signup_password}', user_email_address = '{$signup_email}', users_interests='{$signup_interest_ids}', user_active='Y', user_date_added=NOW()"; mysql_query($users_insert); header('Location:login.php?signup=success'); } } ?> <html> <head> <title>Register</title> <link href="css/style.css" rel="stylesheet" type="text/css" /> </head> <body > <div align="center"><BR><BR><BR> <div style="width:50%; "> <form name="frmSignup" action="sign_up.php" method="post"> <input type="hidden" name="task" value="singup_do"> <table width="100%" border="0" cellspacing="4" cellpadding="4" align="center"> <? if ($error_msg!='') {?> <tr><td> </td><td class="tahoma10rednormal"><?=$error_msg?></td></tr> <? }?> <tr><td width="20%" valign="top">Username : </td><td><input name="user_username" type="text" class="textfield" size="35" value="<?=$signup_username?>"/><? if ($signup_username_msg!='') { echo '<BR><span class="tahoma10rednormal">' . $signup_username_msg.

I have some code that I use elsewhere that works to make Excel exports. When I moved the code over to my custom report page, the Excel chart contains an error saying that $csv_output is undefined and so is $data (both variables toward the end of the page). I tried declaring the variables ($csv_output = ''; and $data = '' above the Excel code, but that didn't work. Can anybody help me out? Code below...

I'm still very new to this forum, so i may be asking this the wrong way. I'm working on a project, but i keep running into the same wall. Whenever i try to load a page with a variable i named on another page, i get an error telling me that it does not know that variable. But how do i make it check for the variable before using it? Example of my code (i only show the first part, as it is the only one relevant): Code: [Select] <html><body> <?php session_start(); if($_SESSION['username']); { $username = $_SESSION['username']; As you can see i have tried to deal with it using an if statement, but i still get the error. I bet there is a very simple way to do this, but i cant see it right now.

Now I know that I can change my php settings to not show the error but I would like to fix it properly. What am I doing wrong? <?php function _com_slider_image_styles() { $styles = &drupal_static(__FUNCTION__); // Grab from cache or build the array. if (!isset($styles)) { if ($cache = cache_get('image_styles', 'cache')) { $styles = $cache->data; } else { // Select all the user-defined styles. $user_styles = db_select('image_styles', NULL, array('fetch' => PDO::FETCH_ASSOC)) ->fields('image_styles') ->orderBy('name') ->execute() ->fetchAllAssoc('name', PDO::FETCH_ASSOC); } } $com_styles = null; foreach($styles as $key => $value){ $com_styles[$key] .= $key; // PROBLEM HERE! } return $com_styles; } ?> Hey Everyone. I've been using a piece of code several times before and its worked fine but now (after updating my php version) I get an error. Heres the code: Code: [Select] if(isset($_GET['id']) == TRUE){ if(is_numeric($_GET['id'])==FALSE) { $error = 1; } if($error == 1){ header("Location: " . $config_basedir); } else{ $validentry = $_GET['id']; } } else{ $validentry = 1; } The line with "if($error == 1){" gets flagged with an error saying: Notice: Undefined variable: error in C:\xampp\htdocs\sites\smd\index.php on line 8 I've used the code before with no problems and uploaded to my web server I also have no errors. What did I do wrong. I hope it isn't a seriously stupid error. Thanks in advance. Hi, I am testing out some simple code while trying out PHP OOP to connect to the MySQL DB.

Hi all, In my server at present php4 is running. upto now it is working fine.Suddenly it is showing lot of errors like Use of undefined constant or Undefined variable:. While trying in Google and all i came to know that the variable should be initialized and bounded by quotes.I checked in 1 file and it worked fine. But my coding is 99% completed and to change in every file is not an easy thing.Can anybody help regarding this Please? Here i'm having 1 more problem also which suffering me for a long time. I'm having one login form in this.That user session is working properly in Chrome but not in Mozilla.Even in Chrome once i try to logoff and relogin again it is behaving like in Mozilla. anybody please help me regarding these 2 issues.Thanks in advance. How do I get my session to be unset? My form looks like this:
foreach ($joined as $i => $qty){
echo "<form action='' method='get' name='yourForm'>";
echo "<button type='submit' name='remove_" . $i . "' value='remove_" . $i . "' class='deletebtn' >X</button>";
echo "</form>";
}
My SESSION is defined like this:
for($i=0; $i<=5; $i++){
if (isset($_REQUEST["element_id_$i"]) ) {
$_SESSION["element_id_$i"] = $_REQUEST["element_id_$i"];
$id = $_SESSION["element_id_$i"];
array_push($_SESSION["element_id"],$id);
}
$id = $_SESSION["element_id"];
}
and the form submits to:
if (isset($_REQUEST["remove_$i"]) ){
unset($_SESSION["quantity[$i]"]);
unset($_SESSION["element_id[$i]"]);
var_dump($_SESSION["element_id"]);
var_dump($_SESSION["quantity"]);
echo "Received variable " . $_REQUEST["remove_$i"];
echo 'TARGET INDEX TO BE REMOVED: ' . $_SESSION["element_id[$i]"] . '<br><br>';
}
The output is:
array(1) { [0]=> string(1) "1" } array(1) { [0]=> string(1) "1" } Received variable remove_1 Hi, I'm trying to create a cms and keep getting an undefined index:action error message. I tried to use isset but then it just threw out a different error. The section of code that is causing the errors is: if ( $_GET['action'] != "login" && $_GET['action'] != "logout" && !$_SESSION['username'] ){ //ITS SHOWING 2 ERRORS WITH ACTION ON THIS LINE login(); exit; } switch ( $_GET['action'] ) { //IT ALSO HAS AN ERROR FOR ACTION ON THIS LINE case 'login': login(); break; case 'logout': logout(); break; I would really appreciate the help as it's been annoying me and i'm having a mental blog. Thanks in advance. I am trying to delete some videos. The videos are echo'd out individually with their own 'delete' input. The input value takes the id of the video, I didn't know of any other work around for that. I'd like to delete the video that corresponds with the button pressed, if that makes sense. Anyways, I would like to delete the video where the video id is equal to the video id of the input or the value of the input pressed. I am positive the way I am carrying this out is not correct, as I am thrown an 'index undefined error'. Here is the disgusting code at hand. Recommendations are appreciated, but please try and keep answers in line with the relevant information given. Thank You.

Hi everyone... please help me with this. I have a gallery that I am working on. Part of that are two files upload.php and preupload.php which upload pics. And it does its job successfully BUT it shows an error 'Notice: Undefined offset: 9 in C:\wamp\www\upload.php on line 34' My line 34 is Code: [Select] if($photos_uploaded['size'][$counter] > 0). My whole code for the upload.php is <?php include("config.inc.php"); // initialization $result_final = ""; $counter = 0; // List of our known photo types $known_photo_types = array( 'image/pjpeg' => 'jpg', 'image/jpeg' => 'jpg', 'image/gif' => 'gif', 'image/bmp' => 'bmp', 'image/x-png' => 'png' ); // GD Function List $gd_function_suffix = array( 'image/pjpeg' => 'JPEG', 'image/jpeg' => 'JPEG', 'image/gif' => 'GIF', 'image/bmp' => 'WBMP', 'image/x-png' => 'PNG' ); // Fetch the photo array sent by preupload.php $photos_uploaded = $_FILES['photo_filename']; // Fetch the photo caption array $photo_caption = $_POST['photo_caption']; while( $counter <= count($_FILES['photo_filename']['tmp_name']) ) { if($photos_uploaded['size'][$counter] > 0) { if(!array_key_exists($photos_uploaded['type'][$counter], $known_photo_types)) { $result_final .= "File ".($counter+1)." is not a photo<br />"; } else { mysql_query( "INSERT INTO gallery_photos( `photo_filename`, `photo_caption`, `photo_category` ) VALUES( '0', '".addslashes($photo_caption[$counter])."', '".addslashes($_POST['category'])."')" ) or die(mysql_error() .

I'm trying to make a simple modification, but I'm getting a a logical error somewhere. The problem is with the one optional variable ($wholesale) that gets sent to the PHP script. If the user has clicked the box on the form and the $wholesale variable has something in it, the message gets sent without an error. But if the user leaves the box blank, nothing is in the variable and PHP has a problem with that. It'll still send the e-mail, but I get a Notice: Undefined index: wholesale in /file/path/on our/sever.com/send_form_email.php on line 35 error. Here's a part of the code: // validation expected data exists if(!isset($_POST['first_name']) || !isset($_POST['last_name']) || !isset($_POST['email']) || !isset($_POST['street_address']) || !isset($_POST['city']) || !isset($_POST['state']) || !isset($_POST['zip']) || !isset($_POST['phone'])) { died('We are sorry, but there appears to be a problem with the form your submitted.'); } $first_name = $_POST['first_name']; // required $last_name = $_POST['last_name']; // required $email_from = $_POST['email']; // required $street_address = $_POST['street_address']; // required $city = $_POST['city']; // required $state = $_POST['state']; // required $zip = $_POST['zip']; // required $phone = $_POST['phone']; // required $wholesale = $_POST['wholesale']; // not required // I don't see why this isn't solving the problem if ( $_POST['wholesale'] == null ) { $wholesale = "."; } ... then the code formats and sends the e-mail out. Any help would be awesome... this is such a simple thing that I honestly can't think of what else to try... |
