PHP - Displaying Error Messages In Form When Php Is Separate File
Hi,
I have a separate form created using Dreamweaver that calls a separate php script when the Submit button is clicked. Currently I am able display form validation messages in a new html page. If the user leaves fields blank, I would like the messages to appear on the form itself instead of in a new page. How do you make the messages from the php form validation code display into the calling html form? I know I could just do this with Dreamweaver but I would like to learn to do this using php. It might be easier to embed the code within the html page but I was thinking that using the separate script would be more secure. My form can be found here. Validation is working but opens a new page: http://www.tallfirshoa.com/adform.htm Thanks! Rob Similar TutorialsHow is it possible, in PHP, to display an error message next to a form input text field if a user is attempting to submit a form with empty fields? Moreover, how is it possible to remove the same error message when the user fills in the input field with the required data and/or refreshes the page? I have 2 files that I am working with: application.php and process.php.
application.php mainly has the HTML of the form. I am very new to learning PHP (I started learning it last week) and I have been searching for hours for a clear answer. I have already tried different methods for generating the error message including: using empty(), !isset, $_POST["name"] = "", etc, and have tried using session_start();, $row, echo, print, and other variables to try and display error message on the page, and I have tried using unset();, and = null, to try and remove the error message once the input field has been filled but all to no avail. Either the method I try only half works, or nothing works, and I cannot pinpoint which is the part that is not working. I only have 2 files to work with, and as an example of what I want to do is:
1. If the first name field is empty when the user clicks submit, an error message should appear next to the input. Is this possible with PHP? How to do it? I have read some methods but they seem to not work. This is what I have got so far:
<?php Hi, When the user creates a contact, then edits the contact that final edited information is shown in a file called "my data.txt". After this, when I select my php file "save_contact_details.php" the details stored in the text file "my data.txt" are not retrieved. How can I retrieve them? At the moment the issue I'm having is that I see no data when I click on "save_contact_details.php" after I filled in all the contact persons information. Feel free to watch this video I recorded to help you understand what I am talking about. https://streamable.com/rbw6p save_contact_details.php code

Edited October 28, 2020 by Alexa Been screwing around on Google for about 3 hours trying to find a tutorial on what I am trying to do with absolutely no luck! I am simply trying to get my test script to echo errors from an array when a form criteria does not validate. This is my final revision which is still not working! Can someone please tell me what I am doing wrong? No matter what I do, I can't get away from this error: Notice: Undefined variable: error in C:\wamp\www\php\form_validation.php on line 13 <?php $o = $error[]; // test echo $o; // test if(!preg_match('/[^0-9A-Za-z]/',$_POST['first_name'])) { $error[] = "Please enter a valid First Name"; ?> <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> First Name:<br /> <input name="first_name" type="text" size="50" maxlength="50" /><br /><br /> <input type="submit" /><br /><br /> </form> hello , i have this code: <?php function error_table($err){ echo"<p><span class='textborder'>$err</span></p>"; } ?> in a separate php file and then call it from another php file , like this : $msg_err='bla bla'; error_table($msg_err); when i click the button it shows the text with its border(the class has a border ,color and 1px) but when i have the code inside other if functions it shows it 2 or 3 times... Hi, I am creating a cms using php and my sql for my website. I have managed to create the majority of it but am having trouble added a menu on each page. It appears on the homepage with the following code: <ul id="headlines"> <?php foreach ( $results['articles'] as $article ) { ?> <li> <h2> <a href=".?action=viewArticle&articleId=<?php echo $article->id?>"><?php echo htmlspecialchars( $article->title )?></a> </h2> </li> <?php } ?> </ul> Once I click on a selection from the menu it takes me to the correct article but there is no menu now. If I try to copy and paste the code from homepage into my viewArticle file it gives me the error messages 'undefined index articles on line 6' and 'invalid argument supplied for for each'. This is the viewArticle code after I pasted in the code from homepage: <ul id="headlines"> <?php foreach ( $results['articles'] as $article ) { ?> <li> <h2> <a href=".?action=viewArticle&articleId=<?php echo $article->id?>"><?php echo htmlspecialchars( $article->title )?></a> </h2> </li> <?php } ?> </ul> <h1 style="width: 75%;"><?php echo htmlspecialchars( $results['article']->title )?></h1> <div style="width: 75%;"><?php echo $results['article']->content?></div> I would really appreciate anybody helping me figure out how I can add the menu onto the viewArticle page. Thanks in advance I have to get the error messages to appear...but for some reason they're not showing up if I leave the forms blank and click submit.

(The vanilla code works fine - the error has arisen through the changes I needed to make). I don't know why this is happening and would appreciate some help please. Thanks in advance for any help.

What I would like to do, is if a error occurs (mysql or php) send me an email with the error message(s), then end the process. Any way I can do this? Right now, I am not sure if any errors occur, but I am thinking that they might be happening. So any way for me to get the error would be awesome! Im trying to create a page that collects personal info from users and registers them. I have a page that contains the registration form which i will call page 1. A second page which I will call page 2, processes the form. A simplified version of page 2 looks like this Code: [Select] <?php if (isset($_POST['submitted'])) { $errors = array(); // Connect to the database. require_once ('config.php'); //Check for errors. //Check to ensure that the password is long enough and is of the right format. if (eregi ("^[[:alnum:]]{8,16}$" , $_POST['password'])) { $b = TRUE; } else { $b = FALSE; $errors[] = 'Please enter a password that consists only of letters and numbers between 8 and 16 characters long.'; } //Check to make sure the password matches the confirmed password. if ($_POST['password'] == $_POST['password2']) { $c = TRUE; $password = $_POST['password']; //Encrypt the password. } else { $c = FALSE; $errors[] = 'The password you entered did not match the confirmed password.'; } //Check to make sure they entered their first name and it's of the right format. if (eregi ("^([[:alpha:]]|-|')+$", $_POST['firstname'])) { $d = TRUE; } else { $d = FALSE; $errors[] = 'Please enter a valid first name.'; } //Check to make sure they entered their last name and it's of the right format. if (eregi ("^([[:alpha:]]|-|')+$", $_POST['lastname'])) { $e = TRUE; } else { $e = FALSE; $errors[] = 'Please enter a valid last name.'; } //Insert data into database. if (empty($errors)) { //query the database. for the sake of simplicity, I wont include the code // Show thank you message echo "<h3>Thank You!</h3> You have been registered"; } else { echo '<font color="red">You could not be registered, please contact us about the problem and we will fix it as soon as we can.</font>'; } //Display error messages. } else {// if errors array is not empty header("Location: page1.php?message=$errors");//Trying to pass the errors array into the url for page1 } } ?> So the idea is to create an array that contains all the errors. Upon querying the database, if the user completed the fields as required, a thank you message is printed. If not, he is redirected to the page containing the form (page 1) and the array containing the errors is transferred to page 1. Now I will include the relevant section of page 1 whihc is supposed to print the error messages. Code: [Select] <?php if(isset($_GET['message']) { echo '<h3>Error!</h3> The following error(s) occured:<br />'; foreach ($errors as $msg) { echo "$msg<br/>\n"; } } ?> I get the following error message when I submit the registration forms with deliberate errors: Error! The following error(s) occured: PHP Error Message Warning: Invalid argument supplied for foreach() in /home/a4993450/public_html/register_page_content.php on line 66 Free Web Hosting Can anyone point out why this error occurs? I'm pretty new to php, and I'm making everything on my web site php-driven. If a warning or error occurs, I don't want the user to see it. Primarily because some of the messages give away hidden file paths that I don't want anyone to know about. I would prefer to redirect all warnings and errors to a log file. If that's not possible, I would like to just hide them. I've googled and can't really find what I'm looking for. PHP.net's manual describes something called display_errors, which doesn't sound bad, but then it says: "Note: This is a feature to support your development and should never be used on production systems (e.g. systems connected to the internet). " http://www.php.net/manual/en/errorfunc.configuration.php#ini.display-errors And I read you can use the @ before any expressions, which I will do if I must, but I don't like it because it's messy. I'd rather there was one thing I could set to say "send all warnings and errors here". Any advice? Thank you! Hello, I am hoping to get some advice on how to make my code work. What I would like to do is display a "you are already subscribed" message if the user experiences error 1062 (duplicate entry) and die, or if it's a different error that occurs I would just like it to display the raw error message and die. I've tried it this and way and that but I'm stumped (obviously I'm also pretty new to this). Here is my code: Quote <?php $con = mysql_connect("localhost"); if (!$con) { die ('Could not connect: ' . mysql_error()); } mysql_select_db("subscribe", $con); $sql="INSERT INTO subscribe_init (id, notes) values ('$_POST[id]','$_POST[notes]')"; if (!mysql_errno() == 1062) echo 'You are already subscribed.'; elseif (!mysql_query($sql,$con)) die ('Error: ' . mysql_errno() . mysql_error()); else echo "Thank you for signing up!"; mysql_close($con) ?> Any advice is greatly appreciated. Thank you! This is what I'm getting...

I don't know much about coding so this may be a dumb question but it has me stumped. I hope somebody can tell me what I'm missing here. This topic has been moved to CSS Help. http://www.phpfreaks.com/forums/index.php?topic=348687.0 One of my tables was hacked by a couple of morons causing me to create a new one The old table was named lner, the new one is named lner3 which has a couple of extra fields Using a playton script to display and manipulate lner3 works just fine but the script used to put detail in gallery pages just DON'T. I basically get a blank page not even the table Remember this is the working script I am still using with my old table until I get the new one working So header and stuff is all fine and it all checks out with CSS and Validation Code: [Select] <body> <div id="head"> <?php // please note $tble = 'lner3'; // Only the above line has changed from //$tble = 'lner'; $brnum = '60112'; include ("../../include/adsense.php"); include_once("../../include/bsgal_conn.php"); ?> </div> <?php $connect = mysqli_connect($host,$account,$password) OR DIE("Error !! Unable to connect to database"); $db = mysqli_select_db($connect,"$dbname") OR DIE( "Unable to select database "); $db="SELECT * FROM $tble WHERE br_no = $brnum OR other_no = $brnum"; if ($result = mysqli_query($connect,$db)) { if (mysqli_num_rows($result)) { while ($row = mysqli_fetch_assoc($result)){ ?> <div id="main"> <table width="410" align="center" border="4" cellspacing="0" cellpadding="1"> <tr> <th>Class</th> <th>C.M.Engineer</th> <th>Arrangment</th> </tr> <tr> <td><?php echo $row['lclas']."/".$row['class2']; ?></td> <td><?php echo $row['cme']; ?></td> <td><?php echo $row['wheel']; ?></td> </tr> </table> </div> </body> </html> So some hints on debugging why it does not work would be most welcome Thanks Roy... What is the most secure way? Having DB connect script in the beginning of every script you need db for, or Having a database.php script containing the script and then including it to all other php. |
