PHP - Why (isset($_post['submit'])) Function Not Working?
I have a simple log in form. By debugging I found that isset post submit function is not responding. It remains on the same page after submitting form. I have googled all the possible solutions to this problem but none worked. Any help is greatly appreciated. The form is in multiplelogin.php file and the code is in multi.php file. After login redirection is to teachers.php file. <?php session_start(); $conn = mysqli_connect("localhost", "root", "", "signup");
if(isset($_SESSION['username'])) {
?>
<head> <link rel="stylesheet" type="text/css" href="bootstrap.css"> <title> Teachers Students Login </title> </head> <body class="bg-secondary"> <div class="container"> <div class="row justify-content-center"> <div class="col-log-5 bg-light mt-5 px-0"> <h3 class="text-center text-light bg-primary py-3 px-5"> Log In </h3>

<?php
ini_set( 'display_errors', 1 );
$password = $_POST['password'];
$stmt = mysqli_stmt_init($conn); header("Location: multilogin.php?error=sqlerror"); exit();
} else { mysqli_stmt_execute($stmt);
$result = mysqli_stmt_get_result($stmt);
if ($pwdCheck == false) {
exit(); $_SESSION['username'] = $row['username']; $_SESSION['email'] = $row['email']; header("Location: teachers.php?login=success");
exit ();
exit();
exit();
else {
exit(); Similar TutorialsI'm not sure why this code isn't working... I've done this many times before and this time it isn't working at all... Here's the code I'm using: <?php if(isset($_POST['submit'])){ if(filter_var($_POST['value1'], FILTER_VALIDATE_EMAIL)){ echo "Value is a valid email address."; } else { echo "Value is NOT a valid email address."; } } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Untitled Document</title> </head> <body> <form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="POST"> <input name="value1" type="text" id="value1" size="40" /> <input id="submit" name="submit" value="Validate Value" type="button" /> </form> </body> </html> I'm wondering whether anything has changed, but I don't see how this couldn't work.

first file to make drop down option form Running into some problems with my code. I am having the user search the Database with either a UAID or the user's full name. It works fine when you input both the UAID and name; however, I want it to work if only one is give (i.e. just the name or just the UAID). I decided to use the isset($_POST) function of php but I am not getting it to work correctly. PHP believe it is set even though it is empty.

Hi, I have a form on my page. <form id="advanced_search" name="advanced_search" method="POST" action="<?php echo $PHP_SELF;?>"> </form> Form submits with a regular button <input type="submit" name="advSearch" id="advSearch" value="Search" /> And i have a detector to see where submit button has been clicked on my next page: if(isset($_POST['advSearch'])) { echo "Button was clicked"; } However, I wanted a custom button for better styling and control. So i replaced my regular button with this now which uses javascript to submit the form. <a class="button" href="javascript:document.advanced_search.submit()" name="advSearch" id="advSearch"><span>Search</span></a> Now the isset($_POST) is not working anymore. Can anyone help please?? Thanks! Hi, just began working with the isset function, and having a few problems with the following code. As you can see I'm trying to assign some variables using the explode function. This is the string that is taken from the form on my index page http://mobsters-fb-apache-dynamic-lb.playdom.com/mob_fb/refresh_stat_manual?user_id=100000898907997&auth_key=e5f4a2308d13346b4bf6e8228e9f50636240bf9f&nocache=1290001265332& $RawHeader = str_replace(' ', '', $_POST['RawHeader']); if (isset($RawHeader)) { $UserID = explode('user_id=', $RawHeader); $UserID = explode('&', $UserID[1]); $UserID = $UserID[0]; $AuthKey = explode('auth_key=', $RawHeader); $AuthKey = explode('&nocache=', $AuthKey[1]); $AuthKey = $AuthKey[0]; } I am new to the isset function so I don't really know if there is anything wrong with it, but if I try echo out both $UserID and $AuthKey it returns nothing. Any suggestions or solutions? Thanks The below should be making it so that in order for "customer reviews" to be visible, you should need the "&review" in the url, but it's coming up regardless if it's in the URL or not. http://ghosthuntersportal.com/store.php?product=2 Code: [Select] elseif(isset($_GET['product'])){ $product_id=$_GET['product']; $sql500="SELECT * FROM $tbl_name3 WHERE product_id='$product_id'"; $result500=mysql_query($sql500); $num_rows500=mysql_num_rows($result500); if($num_rows500==0){ $average_rating=0; } else{ while($row500=mysql_fetch_array($result500)){ extract($row500); $total = $total + $review_product_rating; $review.=' <div class="review_container"> <div>'.$review_product_rating.'

When I declared both of them even AFTER my if statement, this is bogus dude, lol this isset stuff is really confusing or am i just not doing it right? Hi there, I have just move hosts with our website and it loads the frontpage but non of the subsequent pages. The site works like this, depending on the variables in the address depends which page and which template are loaded into it. If the template is "ros" it loads rosettes template, if it is "tro" it loads trophy template, and then the name of the item, ie "hazel" will load up the hazel product page. All it is doing at the moment is loading the home.php page. The code to do this is below: <? if (!isset($template)) {include ("static/home.php");} else if (isset($id)) { if (!file_exists("site_templates/$template.php")) { echo "OOPS! <P> The template you have requested does not exist!<BR><BR><BR><BR><BR><BR>"; }elseif (file_exists("site_templates/$template.php")) { include ("site_templates/$template.php"); } } ?> It worked with our last host, but refuses to work now. Is there someone out there that can help. Thanks in advance, Phil Im trying to use an if isset to stop my error messages displaying before they submit the form it worked on another part of my website but wont work for this, It just wond submit the form at all when i click submit here is the code: <html> <head> </head> <body> <form action="contact.php" method="post"> <fieldset> <legend>Contact Us</legend> Your Email:*<br> <input type="text" name="email"><br> Subject:*<br> <select name="subject"> <option value=""></option> <option value="1">Recruitment</option> <option value="2">Absense</option> <option value="3">Enquiry</option> </select> <br> Message:*<br> <textarea name="message" cols="50" rows="5"></textarea><br> <?php require_once('recaptchalib.php'); $publickey = "6LeB8LwSAAAAAKwvC3HWJNwWw9vYiSEkvFEvDduD"; // you got this from the signup page echo recaptcha_get_html($publickey); ?> <br> <input type="submit" value="Send Email"> </form> Required fields are marked with a *<br><br> <?php if(isset($_POST['Submit'])){ $email = $_POST['email']; $subject = $_POST['subject']; $message = $_POST['message']; $to = "nathan_k_boothby_1994@hotmail.co.uk"; //checcking that all relevent information is entered and correct if(!$message || !$email) { $errmessage ="Please fill in all required data."; } require_once('recaptchalib.php'); $privatekey = "6LeB8LwSAAAAAA_0IIEnAxL5uOau0TBm83Iog7Ey"; $resp = recaptcha_check_answer ($privatekey, $_SERVER["REMOTE_ADDR"], $_POST["recaptcha_challenge_field"], $_POST["recaptcha_response_field"]); if (!$resp->is_valid) { $errmessage ="The text you wrote did not match the image."; } //Sending the email if nothing is wrong if(!$errmessage) { header("location:send.php?to=".$to."&subject=".$subject."&email=".$email."&message=".$message.""); }else{ echo $errmessage; } } ?> </fieldset> <br><br><br> </body> </html> And here is a link to the page: http://valiantflight.comlu.com/emailer/contact.php Any help will be greatly appriciated, Thanks, Blink359 I am an absolute beginner in php & am trying to validate a form using javascript. Problem is I am checking if the textbox is left empty before the user clicks on the submit button(using javascript). On the other hand i'm using isset function of php for the same submit button so that it does not run the code unless and until the button is clicked. Due to this, the default value of text box is being entered into database. How do i prevent this? Is there an alternate function to isset for such an event? Here is a sample code Code: [Select] <?php if(isset($_POST[sub])) $sql="insert into testing values('$_POST[txt1]')"; $exec = mysql_query($sql); ?> <script type="text/javascript"> function check() { var a = document.getElementById('add'); if (a.value = "") { return false; } } </script> <form action="add.php" method="post"> <input type="text" name="txt1" id="add"><br> <input type="submit" name="sub" value="Click to Add" onclick = "check();"> </form> I'm using ghost text technique on my page instead of labels so the text boxes have different values at different instances and hence I cant use !empty function either. How do i unset the submit button so that it does not run the script further? Sorry for the miss spell on correctly counldn't edit the title
I need to have the following 3 varibles checked to see if they are set and if not display an error saying "All fields need to be filled in." My problem is that it's not working. Did I mess up on my if statement? $tempneeded $lowtemp $gallons
<?php
$tempneeded = $_POST['tempneeded'];
$lowtemp = $_POST['lowtemp'];
$gallons = $_POST['gallons'];
htmlspecialchars($tempneeded, ENT_QUOTES, 'UTF-8') . ' ' .
htmlspecialchars($lowtemp, ENT_QUOTES, 'UTF-8') . ' ' .
htmlspecialchars($gallons, ENT_QUOTES, 'UTF-8') . ' ' .
$wgd = .5;
$tempdiff = $tempneeded - $lowtemp;
$wattsneeded = $tempdiff * ($gallons * $wgd);
if (!isset ($lowtemp,$tempneeded,$gallons))
{
echo "<b>All fields need to be filled in.</b>";
} else {
echo "<b>You will need a total of $wattsneeded watts to rasie your tempature $tempdiff degress, from $lowtemp to $tempneeded.</b></td></tr>";
}
?>
Edited by msebar, 08 October 2014 - 01:43 PM. I've tried both of these methods, but neither are working. The if statement fails every time. Code: [Select] if(isset($_POST['submit'])){ Code: [Select] if(isset($submit)){ This is the form: Code: [Select] <form id="form1" name="form1" method="post" action="join.php"> <label><span> <input name="email" type="text" class="keywords" id="textfield" maxlength="50" value="Join my mailing list..." onclick="make_blank();" /> </span> <input name="submit" type="image" src="images/search.gif" class="button" onclick="return checkmail(this.form.email);"/> </label> </form> soory guys .. actually i am trying to add pagination in script.. but its not pagging.

Hello! This may sound like a stupid question but i have been trying to get this working all day and its driving me crazy.
Ive been asked to take over development of this project, he sent me his code and its a little out of date so im trying to update it. Here is what i cant work out.
I have this little snippet of code:
if ($page == "showthread"){
showThread();
}
There are several more like that, but you dont need a whole list.
That code seems to be throwing up this error when i go to that specific page:
Notice: Undefined index: error in .....
All well and good, i would usually do this:
if (isset($page) == "showthread"){

Thats fine and dandy, the error goes away. But now, when i go to that page, it redirects me and gives me my error message for a non-existing page.
Its really frustrating me. Can you help me fix this little error?
I have a long list of variables with form fields inserted into them like this: $page_id = $_POST['exclude']; I just turned on WP_Debug just to see which error messages would come up and to my surprise it wasn't that bad, the most error messages were "Call to Undefined function". The solution to this problem is simple, all I have to do is wrap an isset around all the form field variables, like this: $page_id = isset($_POST['exclude']); My question is, is this really necessary or considered as good practice? Should I now go ahead and wrap to all the variables in that long list an isset around? Or should I just turn WP_Debug off again and leave it as is? I personally would like to adopt to the good practice way, but I don't know how much of an advantage it is to wrap an isset around every single form field variable. Any suggestions? Hello, its a bit difficult to explain the issue that I have but I will try my best. I have this small code $message = $_POST['message1']; in my php code and message1 is the name of a textarea in my page. i also have another textarea called message2 in my page. what I need to do is to use the message1 and message2 in the $message = $_POST function. For example: $message = $_POST['message1'] + $_POST['message2'] or anything that is acceptable in PHP coding and works in PHP. I hope I havent confused you guys and you undersstood what I mean... Thanks Hi, I was going to through a PHP tutorial, and came across a form validation user defined function . Below is an example.. Code: [Select] function check_required_fields($fields){ $field_errors = array(); foreach ($fields as $requried_fields) { if (!isset($_POST[$requried_fields]) || (empty($_POST[$requried_fields]) && $_POST[$requried_fields] != 0)) if (!isset($_POST[$fieldname]) || (empty($_POST[$fieldname]) && $_POST[$fieldname] != 0)) { $errors[] = $requried_fields; } } return $field_errors; } When the user defined function was called they added an $_POST and the end of the user defined function. Here is a the code snipped of how it looks Code: [Select] $errors = array(); // perform validations on the form data $required_fields = array('username', 'password'); $errors = array_merge($errors, check_required_fields($required_fields, $_POST)); If the validation can be preformed with out the $_POST, why bother inserting it? Thanks! Hello pros. I've been working on a website, and i just figured out that a thing is completely wrong. I am entering the website with: "website.com/something.php?name='Hello/system/root/advance.exe'" but somehow the $_POST['name'] is null... My current php code which just prints that post data: Spoiler <?php $postedFileName = $_POST["name"]; echo $postedFileName; /*#-- Here it doesnt echo anything --#*/ ?> |
