So far i have such code
<form action="register.php" target="login" type=post>
<label for="name">Account </label><br><br>
<input type=text id="name" name="account" size=20 maxlength=<?php Echo MaxNameLength; ?> /><br><br>
<label for="name">Password</label><br><br>
<input type=text id="name" name="password" size=20 maxlength=<?php Echo MaxNameLength; ?> /><br><br>
<button type=submit>Register</button>
</form>
I placed it inside an IFrame but when i try to use php with such code:
<?php
If (IsSet($_GET["account"]["password"])) { $Account = $_GET["account"]; $Password = $_GET["password"];
$AllRight = True;
For ($I=0; $I<StrLen(WrongChars); $I++) {
If (StrPos($Account, SubStr(WrongChars,$I,1))) {
Echo "<p>Your Name musn't contain the char \"".SubStr(WrongChars,$I,1)."\"</p>";
$AllRight = False;
}
}
If (file_exists(AccountFilesPath.$Account.AccountFilesEnding)) {
Echo "<p>This Account already exists!</p>";
$AllRight = False;
}
If ($AllRight) {
$Text .= "$Password ";
File_Put_Contents (AccountFilesPath.$Account.AccountFilesEnding, $Text);
if(!file_exists(AccountFilesPath.$Account.AccountFilesEnding)) {
echo "<p>Error during account cration!</p>";
}
Echo "<p>This Account is created succesfully!</p>";
}
}
?>
yet the responce im getting is a fresh registration page with no work done...
i want my iframe to individually register text files like (user1.txt) with ($Password) inside. Along with having a link to the login, and upon login have a User Control Panel.
I don't understand why you are using an iframe for this but I can see that you use $_GET in your php when your form submits $_POST (type="post")
Try changing that in your PHP code and see if it works
Edit*
As stated in the comments this is not a $_GET index $_GET["account"]["password"]
Let's say you stick with POST since your html form submits a POST,you must use something like this:
if(isset($_POST["account"]) && isset($_POST["password"]))
And to be sure what variables you get from your form, I recommend you to print your Post array before any manipulation.
print_r($_POST);

I'm trying to make a website that automatically uses this script to get amount of bitcoin in an wallet :
<?php
$address = $_GET["address"];
$satbalance = file_get_contents('https://blockchain.info/q/addressbalance/'.$address.'');
$btcbal = ($satbalance) / 100000000;
echo $btcbal;
?>
and I'm trying to make page that has my clients username and password in textarea box and when I enter the bitcoin wallet address from my user to check the balance from multiple input boxes and show the value in the box in front of address box.
Image of the page that needs this job done
How can I get the response from the form and display in another box or variable.
Thanks.
Wrap the fields in a form tag and submit to the same page.
Using your code example, this example show a simple form and handling the POST with PHP. This hasn't been tested but is an example of how to handle a post using the $_POST super global.
<?php
$btcbal = null;
// Check if there is POST data
if (!empty($_POST)) {
$address = $_POST['address'];
$satbalance = file_get_contents('https://blockchain.info/q/addressbalance/'.$address.'');
$btcbal = ($satbalance) / 100000000;
}
?>
<form method="post">
<input type="text" name="username">
<input type="password" name="password">
<input type="text" name="btc_address">
<button type="submit">Submit</button>
</form>
<p>Balance: <?php echo $btcbal ? $btcbal : 'N/A'; ?></p>
I have a form.php file that redirects to a sendformdata.php file when I submit the form. However, I can't get the sendformdata.php file to display an error message within the form when the proper fields aren't filled out.
I am simply redirected to the include file, db_connect.php, which shows up as a blank page. How can I get the page to stay on form.php and display an error message in html? This is my current sendformdata.php file:
<?php
include_once('db_connect.php');
$lokotitle = $description = $category = $showyourname = $yourname = $lat = $lng = "";
if($_SERVER['REQUEST_METHOD'] == 'POST'){
$lokotitle=$_POST['lokotitle'];
$description=$_POST['description'];
$category=$_POST['category'];
$showyourname=$_POST['showyourname'];
$yourname=$_POST['yourname'];
$lat=$_POST['lat'];
$lng=$_POST['lng'];
// Validation will be added here
if(empty($lokotitle)) {
$error_message = "Please input a Loko title.";
?><script>$('#notitle'.text($error_message));</script><?php
exit;
}
if(!isset($error_message)){
//Inserting record in table using INSERT query
$insqDbtb="INSERT INTO `new`.`web_form`
(`lokotitle`, `description`, `category`, `showyourname`, `yourname`, `lat`, `lng`) VALUES ('$lokotitle', '$description', '$category', '$showyourname', '$yourname', '$lat', '$lng')";
mysqli_query($link,$insqDbtb) or die(mysqli_error($link));
?><script>window.location.href = "../index.php"; </script> <?php
exit;
}
}
?>
This is a section of form.php that I am trying to display an error message in:
<form class="form-horizontal" role="form" action="handleform/sendformdata.php" method="POST">
<legend></legend>
<div class="form-group">
<label for="lokotitle" class="col-sm-2">Loko Title</label>
<div class="col-sm-4">
<input type="text" class="form-control" name="lokotitle" id="lokotitle" placeholder="Title">
<span id="notitle"></span>
</div>
Thanks in advance for the help!
I recommend you to use both html5 required attribute which will force the user to enter the data. But remember the user can bypass front end validation (by means of inspect element), hence back end validation is also necessary.
Use required attribute like:
<input type="text" required />
You can try this
if(empty($lokotitle)) {
$error_message = "Please input a Loko title.";
echo "<script>
document.getElementById('#notitle').value='".$error_message."';".
"</script>";
exit;
}
Let me know if this solves your problem
I am using a contact form on my website and I want it to use a javascript function to use a popup box to tell the user that they have not filled all fields. I have this code:
<?php
$action=$_REQUEST['action'];
if ($action=="") /* display the contact form */
{
?>
<form action="" method="POST" enctype="multipart/form-data">
<input type="hidden" name="action" value="submit">
*Name:<br>
<input name="name" type="text" value="" size="30"/><br><br>
*Email:<br>
<input name="email" type="text" value="" size="30"/><br><br>
*Message:<br>
<textarea name="message" rows="7" cols="30"></textarea><br>
<input type="submit" value="Send email"/>
</form>
<script type="text/javascript">
function requiredFields() {
alert("Please fill in all fields!");
}
<?php
}
else /* send the submitted data */
{
$name=$_REQUEST['name'];
$email=$_REQUEST['email'];
$message=$_REQUEST['message'];
if (($name=="")||($email=="")||($message==""))
{
echo "requiredFields();";
}
else{
$from="From: $name<$email>\r\nReturn-path: $email";
$subject="Message sent using your contact form";
mail("email#email.com", $subject, $message, $from);
echo "Email sent!";
}
}
?>
</script>
However, the website displays this error:
Fatal error: Call to undefined function requiredfields() in /home/a8502709/public_html/test/contact.php on line 46
The line above is the line that it echoes the calling for the function. How can I properly call the function in echo?
You didn't quote your echo output:
echo requiredFields();;
It should be:
echo "requiredFields();";
Otherwise you're telling PHP to execute the requiredFields() function, which doesn't exist in PHP. Hence the error. Your intent here is to tell the JavaScript on the rendered page to execute the function. So as far as PHP is concerned you're just outputting a string to the page.
Note also that this is a syntax error:
echo "Email sent!";
What this will do is emit the following to the JavaScript in your <script> block:
Email sent!
Which, of course, isn't valid JavaScript. You probably meant to output that somewhere else in the page.
Edit: You also seem to have a significant logical error in your code. If you remove the unrelated lines, your structure is essentially this:
if ($action=="") /* display the contact form */
{
?>
<script type="text/javascript">
<?php
} else {
echo "requiredFields();";
}
?>
</script>
So... You only open the <script> tag in the if block, but you use that tag in the else block. By definition both can't execute. Only one or the other. So you're going to have to restructure this a bit.
Maybe close the <script> tag in the if block too, and then open another one in the else block? Or have multiple if/else blocks for the HTML and for the JavaScript? There are a couple of different ways to structure this. But you should see what I'm talking about when you view the page source in your browser. You'll see that, in the event of the else block, you're never creating a <script type="text/javascript"> line and therefore aren't actually executing any JavaScript.
Though, thinking about this some more, it doesn't make sense at all to have the JavaScript start in the if block. Since only the else block uses it. You can't define the function in the if and then try to use it in the else because, again, by definition only one or the other would execute. Maybe just move all of the JavaScript to the else:
<?php
$action=$_REQUEST['action'];
if ($action=="") /* display the contact form */
{
?>
<form action="" method="POST" enctype="multipart/form-data">
<input type="hidden" name="action" value="submit">
*Name:<br>
<input name="name" type="text" value="" size="30"/><br><br>
*Email:<br>
<input name="email" type="text" value="" size="30"/><br><br>
*Message:<br>
<textarea name="message" rows="7" cols="30"></textarea><br>
<input type="submit" value="Send email"/>
</form>
<?php
}
else /* send the submitted data */
{
?>
<script type="text/javascript">
function requiredFields() {
alert("Please fill in all fields!");
}
<?php
$name=$_REQUEST['name'];
$email=$_REQUEST['email'];
$message=$_REQUEST['message'];
if (($name=="")||($email=="")||($message==""))
{
echo "requiredFields();";
}
else
{
$from="From: $name<$email>\r\nReturn-path: $email";
$subject="Message sent using your contact form";
mail("email#email.com", $subject, $message, $from);
echo "alert('Email sent!')";
}
?>
</script>
<?php
}
?>
Honestly, this mix of PHP/HTML/JavaScript you have here is a little confusing. Which isn't making this any easier for you. You'll probably want to re-structure this a bit once you get it at least working.
I have simple form:
<div class="form-style-2">
<form action="" name="formular" id="formular" method="GET">
<label for="actual_position"><span>From: <span class="required"></span></span><input name="actual_position" type="text" maxlength="512" id="actual_position" class="searchField"
<?php if(!empty($actual_position)){ ?>
value="<?php echo $_GET['actual_position']?>"
<?php
}else {
?> value = ""; <?php
} ?>/></label>
<label for="final_position"><span>To: <span class="required"></span></span><input name="final_position" type="text" maxlength="512" id="final_position" class="searchField" <?php if(!empty($final_position)){ ?>
value="<?php echo $_GET['final_position']?>"
<?php
}else {
?> value = ""; <?php
} ?>/></label>
<input type="submit" value="Find path" />
And another multiselect in form who gets values form url link and compere with database and get som results. Here is a code:
<table width= "570px">
<tr><td width="200px" style="align:center"><b>Waypoints:</b> <br>
<tr><td width="370px"><select style="float:center; margin-left:5px" multiple id="waypoints">
if(!empty($urls)){
foreach($urls as $url){
if($result = $conn->query("SELECT * FROM $table where $ID = '$url' "));
$atraction = $result->fetch_array(); ?>
<option value="<?php echo $atraction['lat']. "," . $atraction['lon']; ?>"
> <?php echo "<b>".$atrction['City']. ", " . $atraction['Name'];?> </option>
<?php
}
}
?>
</select></td></tr>
<br>
</table>
</form>
And getting ID-s from url code:
if(!empty($_GET[$ID])){
$urls = $_GET[$ID];
foreach($urls as $url){
// echo $url;
}
}
... and after submit, it Post to URL some variables like this:
http://127.0.0.1/responsiveweb/travel.php?actual_position=Paris&final_position=Praha&ID[]=23&ID[]=15&ID[]=55
... very important for me are ID-s values ... but when I change for example actual position and then submit I lost my ID-s and I get something like this: http://127.0.0.1/responsiveweb/travel.php?actual_position=Berlin&final_position=Praha
Can you help me how to get after clicking on submit button full url link? Thanks
I had some trouble understanding your question OP, but I think I understood somehow what you ment, so I decided to try giving you a answer.
I have re-written your code, and tried to make somehow better code-structure. I have also used form method POST in my example, so you can see how you can change the get data on the redirection url.
See my code example here: http://pastebin.com/wQ7QCBmt
I also decided to use the form method POST instead of GET, so you can easily do back-end tasks, and extend your link if neccessary. You could also add more data to the link even when using GET. You could add an hidden input inside your form, example:
<input type="hidden" name="more_data" value="a_value" />
everybody.
I have the following situation:
I have:
http://example.com/ and http://example.com/new
In example.com, I have some forms that I load in example.com/new domain with fancybox iframe.
My form, basically shows some fields for the user to enter his pessoal data, like name, phone and etc... After he submit that, I show some user agreement terms that comes from database and a checkbox for the user to say that he agree with the terms.
After he check and submit, I want to alert some sucess message and the fancybox modal/iframe to close and thats it.
In the form page, i've loaded jquery, and bootstrap. So, when the user agree, I print:
<?php
echo "
<script>
alert('Some success message!');
$(document).ready(function(){
parent.$.fancybox.close();
});
</script>
";
?>
I have three forms, in one, works, in the other two, i get:
Error: Permission denied to access property '$'
The only difference between the form that works and the other two, is that in the form that works, i don't have the agreement terms coming from database, only the checkbox.
I could put my entire code here, but would be a giant question. But if you guys need, I can update.
Sorry for my english and forgive-me if I was not clear.

This is a browser security thing. While there's a few ways around it, the best one is probably to use the postMessage API.
On your example.com parent page, add some code like this:
function handleMessageFromiFrame(event) {
alert('Some success message: ' + event.data);
//$.fancybox.close();
}
window.addEventListener("message", handleMessageFromiFrame, false);
And, then on your child example.com/new iframe, add code like this:
var parentOrigin = "*"; // set to http://example.com/ or whatever for added security.
function sendMessageToParent(){
parent.postMessage("button clicked", parentOrigin);
}
$('#submit-btn').click(sendMessageToParent);
Here's an example of it in action:
Parent example.com page: http://jsbin.com/hiqoyevici/1/edit?html,js,output
Child example.com/new iframe: http://jsbin.com/goferunudo/1/edit?html,js,output
When you click the button in the child page, it uses postMessage to notify the parent. Then the parent listens for the message and does whatever action you want.
