I have created custom contact from with Ajax and implemented in WordPress. Now I want to add custom captcha script.
Currently I am using this captcha script for my contact form 9lessons phpcaptcha but after implementing I am getting verification Wrong alert box every time. I don't know whats wrong in my code.
FYI: I have created plugin file so I have added all code in one file.
My Code:
<?php
session_start();
$cap = 'notEq';
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
if ($_POST['captcha'] == $_SESSION['cap_code']) {
// Captcha verification is Correct. Do something here!
$cap = 'Eq';
} else {
// Captcha verification is wrong. Take other action
$cap = '';
}
}
?>

I will appreciate if you help to sort out this issue.
Thanks.
As I seen your code, it will not call the captcha verification.
change the submit button name to some thing else otherwise the jquery submit will not triggered.
Verify the captcha using ajax on form submit event.
When it captcha code is correct then again send the ajax request to store the data.if its incorrect refresh the captcha image.

I wanna submit/write content to a .txt file and i have to used php to do it, but i don't wanna open the php page and wanna stay on the same page.
How can I do this?
Index.html
<form action="writer.php" method="POST">
<input name="field1" type="text" />
<input name="field2" type="text" />
<input type="submit" name="submit" value="Save Data">
</form>
writer.php
<?php
if(isset($_POST['field1']) && isset($_POST['field2'])) {
$data = $_POST['field1'] . '-' . $_POST['field2'] . "|| \n";
$ret = file_put_contents('mydata.txt', $data, FILE_APPEND | LOCK_EX);
if($ret === false) {
die('There was an error writing this file');
}
else {
echo " written to file";
}
}
else {
die('no post data to process');
}
?>`
You could simply use iframes, easier alternative to AJAX.
<iframe name="panel" style="display:none;"></iframe>
<form action="writer.php" method="POST" target="panel">
<input name="field1" type="text" />
<input name="field2" type="text" />
<input type="submit" name="submit" value="Save Data">
</form>
...and as everyone here is yelling, consider learning AJAX.
create a php file with following in it.
<?php
if(isset($_POST['SubmitButton'])){ //check if form was submitted
$input = $_POST['inputText']; //get input text
file_put_contents('mydata.txt', $input, FILE_APPEND | LOCK_EX);
$message = "Success! You entered: ".$input;
}
?>
<html>
<body>
<form action="" method="post">
<?php if(isset($message)) echo $message; ?>
<input type="text" name="inputText"/>
<input type="submit" name="SubmitButton"/>
</form>
</body>

where i am wrong in this code
and how can i achieve my goal
Any help will be appreciated
changes you need to make:
add jquery as a dependency as you are using $.ajax utility function which is provided by Jquery.
As you are using Jquery, you could use its selectors for getting values of elements and binding functions to dom elements. I have commented it in the source code.
You are using a form with a submit button and executing the ajax call on click of it. But you need to prevent the page from submitting the form by preventing the default behavior of the submit button. Refer event.preventDefault();
Move the php ajax response part to the top and call exit() once your response is complete. Else your ajax response will include the whole page html source also.
.
<?php
include('conn.php');
if (isset($_POST['Update'])) {
$name = $_POST['name'];
$last_name = $_POST['last_name'];
$insert = "insert into ajaxsave values('$name','$last_name')";// Do Your Insert Query
if(mysql_query($insert)) {
echo "Success";
} else {
echo "Cannot Insert";
}
//Call exit as your ajax response ends here. You dont need the html source along with it.
exit();
}
?>
<html>
<head>
</head>
<body>
<form action="" method="post">
<input type="text" name="name" id="name" value="" />
<input type="text" name="last_name" id="last_name" value="" />
<input type="submit" name="Update" id="update" value="Update" />
</form>
<div id="div1" style="width:300px;height: 50px;background-color: yellow;" >
</div>
<!-- include jquery dependeny before your js code block -->
<script src="https://code.jquery.com/jquery-latest.js"></script>
<script>
$("#update").on("click",function(event) {
//Prevent Default submit button behavour. Prevent the form from submission.
event.preventDefault();
// using Jquery selectors for better readability of code.
var name = $("#name").val();
var last_name = $("#last_name").val();
$("#last_name").css("background-color","green");
$.ajax({
type:'POST',
data:{name:name,last_name:last_name,Update:true},
url:'demo.php',
success:function(data) {
alert(data);
}
});
});
</script>
</body>
</html>
You send two parameters in "dataString" variable, and then in php check undefined variable "Update"
So, just replace string
if (isset($_POST['Update'])) {
to
if (isset($_POST['name']) && isset($_POST['name'])) {
And add this line to tag
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>

the <?php echo $_SERVER["PHP_SELF"];?> on the second form calls the php at the bottom of the page this is the one that is working it is the upload_logo.php that is not currently working any help would be much appreciated
You're trying to submit 2 forms at once. That can't work, as your browser can only be directed to 1 page at a time, so your attempt to submit the upload form with JavaScript is cancelled by the contact form being submitted. I'd suggest that you move the file input into the same form as the contact fields, and handle them both in your "the user has submitted the form" section.
Something like this should do the trick:
<?php
if (!isset($_POST["submit"]))
{
?>
<div id="loginborder">
<div id="login">
<form enctype="multipart/form-data" method="POST">
<input name="userfile" type="file" />
<input type="hidden" name="subject" value="Can you create me a Contributors account">
<input type="text" name="first_name" id="first_name" placeholder="Name">
<input type="text" name="company" id="company" placeholder="Company Name">
<input type="checkbox" id="tc" onclick="checkbox()">
<input type="submit" id="submit" name="submit" value="Register" disabled>
</form>
</div>
</div>
<?php
}
else
// the user has submitted the form
{
// Check if the "subject" input field is filled out
if (!empty($_POST["subject"]))
{
sleep(5);
$subject = $_POST["subject"];
$first = $_POST["first_name"];
$company = $_POST["company"];
$therest = "First name= $first" . "\r\n" . "Company= $company" . "\r\n";
echo "$therest <br>";
$first = wordwrap($first, 70);
mail("careersintheclassroom01#gmail.com",$subject,$name,$therest,"subject: $subject\n");
echo "Thank you for sending us feedback";
header( "refresh:5;url=index.php" );
}
if (isset($_FILES['userfile']['name'])) {
$uploaddir = "./images/";
if (!file_exists($uploaddir)) {
mkdir($uploaddir, true);
}
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);
move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile);
echo "<br />";
echo " <b>Your media has been uploaded</b><br /><br /> ";
}
}
?>
</body>
try this after $uploadfile = ...
move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile);
when you submit 2nd form e-mail would be generated becausue it triggers if(isset($_POST["subject"])) condition and the code will follow the next commands.
But when you submit 1st form, it will call onsubmit="alert(); function and that function again submits the same form because of these.
function alert()
{
document.getElementById("upload").submit();
}
so you are just triggering a never ending loop.
My solution is
<script type="text/javascript">
function alert()
{
function checkbox(){
if (document.getElementById("tc").checked == true)
document.getElementById("submit").disabled = false;
else
document.getElementById("submit").disabled = true;
}
}
$('input[placeholder],input[placeholder],input[placeholder],input[placeholder],input[placeholder]').placeholder();
</script>
I'am not 100% sure about your requirement. hope you can get the point what i'am making. gl!
So I'm basically trying to create an HTML form that will
process my login through php POST method
close my login lighbox with javascript, or display an error (right now I'm using JS to change an invisible form value under the login form.
HTML
if (isset($_GET['error'])) {
echo '<p class="error">Error Logging In!</p>';
}?>
<br />
<form action="process_login.php" method="post" name="login_form">
Email: <input class="searchform" type="text" name="email" size="20"/><br />
Password: <input class="searchform" type="password"
name="password"
id="password" size="20"/><br />
<input type="button" class="searchform"
value="Submit" size="40" style="height:45px; width:90px"
onclick="formhash(this.form, this.form.password);" />
<input type="text" id="errorbox" style="height:45px; width:180px" value=""><br>
</form>
here's the php file:
if (isset($_POST['email'], $_POST['p'])) {
$email = $_POST['email'];
$password = $_POST['p'];
if (login($email, $password, $mysqli) == true) {
// Login success
echo "<script>document.getElementById('light').style.display=
'none';document.getElementById('fade').style.display= 'none'</script>";
} else {
// Login failed
echo "<script>document.getElementById('errorbox').value='Error'</script>";
}
} else {
// The correct POST variables were not sent to this page.
echo 'Invalid Request';
}
I know I'm not doing this right, I'm just not sure HOW to do it at all...
Well, yes, technically you can do that, but it is a VERY bad practice, and extremely not clean.
what you'd prefer to do is use Ajax, and do those JS actions in it's success callback:
Note: you will need to include the jQuery lib in your scripts.
Another none: if you don't have PHP 5.4 on your server, just remove the second callback function, and handle all the scenarios in the success callback
!(function($){
$(function() {
$('#submitBtn').on('submit', function(){
$.post('process_login.php', $('form[name="login_form"]').serialize(), function(data){
//data is a json object which contans the reponse
data = $.parseJSON(data);
$("fade").fadeOut();
$("light").fadeOut();
},
function(data){//error callback
data = $.parseJSON(data);
if(data.forbidden){
$("#errorBox").html("Error!");
}
else if(data.error){
$("#errorBox").html("Invalid request!");
}
});
});
});
})(window.jQuery);
HTML:
<form name="login_form">
<div>
<input type="text" name="email" placeholder="email">
</div>
<div>
<input type="password" name="p" placeholder="password">
</div>
<div>
<input type="button" id="submitBtn" value="Login">
</div>
</from>
PHP:
$response = array();
if (isset($_POST['email'], $_POST['p'])) {
$email = $_POST['email'];
$password = $_POST['p'];
if (login($email, $password, $mysqli) == true) {
http_response_code(200);//HTTP OK, requires php 5.4
$response['success'] = true;
} else {
// Login failed
$response['forbidden'] = true;
http_response_code(401);//HTTP forbidden
}
} else {
// The correct POST variables were not sent to this page.
$response['error'] = true;
http_response_code(400);//HTTP bad request
}
echo json_encode($response);
add onsubmit event attribute to the form:
<form onsubmit="return validate();">...
where validate() is a js function that closes lightbox and returns true if form is ok, or displays errors and returns false if form is bad.
Hello I am wondering if this is possible? Having two different forms on the same page using the jquery post to send it php to do some checking. The first from works flawlessly, however when I go to the second form I get an error saying it is an undefined variable but I am using the exact same method I used for the first form. It will load anything echoed in the php page for the feed form but will not echo back what I am typing in. Is there a better, more correct way to do it?
This is not for a real site, just testing for a project I am working on.
HTML:
<form action="php/signup.php" method="post" class="form-inline" name="signupForm">
<input type="text" maxlength="20" name="username" id="user_in">
<input type="password" maxtlength="20" name="password" id="pass_in">
<input type="submit" name="submit" Value="Sign Up">
</form>
<div id="feedback"></div> <!-- Feedback for Sign Up Form -->
<br /><br />
<form name="feedForm">
<input type="text" id="feed_in" name="feed_me_in" placeholder="feed">
<div id="feedme"></div> <!-- FEEDback for feed form -->
</form>
<script src="js/jquery-1.9.1.js"></script>
JavaScript:
<script>
$(document).ready(function() {
$('#feedback').load('php/signup.php').show();
//SIGN IN FORM
$('#user_in, #pass_in').keyup(function() {
$.post('php/signup.php', { username: document.signupForm.username.value,
password: document.signupForm.password.value },
function(result) {
$('#feedback').html(result).show
});
});
$('#feedme').load('php/feed.php').show();
//FEED FORM
$('#feed_in').keyup(function() {
$.post('php/feed.php', { feed: document.feedForm.feed_me_in.value },
function(result) {
$('$feedme').html(result).show
});
});
});
</script>
PHP for Feed Form:
<?php
$feed = mysql_real_escape_string($_POST['feed']);
if(isset($feed)) {
echo $feed;
} else {}
?>
PHP for the Sign Up Form:
<?php
if(isset($_POST['username'])) {
include_once('connect.php'); //Connect
$username = mysql_real_escape_string($_POST['username']);
$sql1 = "SELECT username FROM users WHERE username='$username'";
$check = mysql_query($sql1);
$numrows = mysql_num_rows($check);
if(strlen($username)<=4) {
echo "Username is too short";
} elseif($numrows == 0) {
echo "Username is available";
} elseif($numrows > 0) {
echo "Username is already taken";
}
} else {
echo "Please type a username";
}
?>
$('$feedme').html(result).show
should be
$('#feedme').html(result).show();
