I do apologise in advance for my lack of knowledge in PHP and HTML. I have scoured the internet for 3/4 days trying to create what is probably a simple system. I need the user to enter a digit before the next page is loaded. I have an IF statement on my page.
1.php
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
<link href="css/style.css" rel="stylesheet" type="text/css" />
<link href="css/reset.css" rel="stylesheet" type="text/css" />
<div id="container">
<div id="authorise">
<form action="2.php" method="post">
<!--Product Comment Box--><br>
<p>Please enter your 4<br> digit authorisation code:<br> <br>
<input type="text" name="digits" />
<input type="submit" name="submit" />
</form>
</div>
</div>
2.php
<?php
if ($_POST['digits'] === '210392')
{echo 'https://www.facebook.com/'
?>
But I need a form first which the user would input the code '210392' and press submit. Then the if statement can take place. I know how to do a form but dont know how to assign that form a variable name 'digits'. All help is appreciated.
A basic form:
<form action="your_file.php" method="post">
<input type="text" name="digits" />
<input type="submit" name="submit" />
</form>
Then in your_file.php:
<?php
if ($_POST['digits'] === '210392') {
// etc.
$_POST is a superglobal array that has all data POSTed to your script. digits in this case is an index in that array. It comes from the name of the input field.
<form action="check.php" method="POST">
<input type="text" name="digits" />
<input type="submit" value="click here" />
</form>
//in check.php
if (isset($_POST['digits']) and $_POST['digits'] == 12345){
header("Location: http://google.com");
}
else {
echo " error !!";
}

and php

<form action="https://scm-intranet.tees.ac.uk/users/l1071039/bobbin/admin.php" method="post">
Password : <input type="password" name="pwd" />
<input type="submit" name="send">
</form>
// admin.php
<?php
if( isset($_POST['pwd']) ){
$pwd = $_POST['pwd'];
}
?>
You first need to create an input with the very important name attribute which you'll use later.
<form method="post">
<input type="password" name="mypassword" />
<button type="submit">Go</button>
</form>
PHP:
//Post method access with $_POST variable:
if ($_POST['mypassword'] == 'my-password') { //Oh, you should probably use SSH and hash the password
//Hooray!
}
Instead of echo, use header.
<?php
if ($_POST['digits'] === '210392')
{
header (loaction:https://www.facebook.com/);
}
?>

So the goal is to take the input from a form append it to the end of the URL and then return the HTML from that page.
I am not entirely sure how to take the forms value (in this case $2) and attach it to the URL.
<html>
<head>
<title>Metar Test</title>
</head>
<body>
<form action="" method="POST">
<p>IACO Code: <input type="text" name="$2" value=""></p>
<input type="submit" name="submit" value="Submit">
</form>
<?php $html=file_get_contents("http://www.metar.mysite.net/metar?id=$2")?>
<?php echo $_POST ["$html"];?>
</body>
</html>
On submit any input from a form with method="POST" will be stored in the $_POST global. You can access it from there and append it to your URL string.
<html>
<head>
<title>Metar Test</title>
</head>
<body>
<form action="" method="POST">
<p>IACO Code: <input type="text" name="iacoCode" value=""></p>
<input type="submit" name="submit" value="Submit">
</form>
<?php
if (isset($_POST["iacoCode"])) {
$html = file_get_contents("http://www.metar.mysite.net/metar?id=" . $_POST["iacoCode"]);
echo $html;
}
?>
</body>
</html>
Using the IF statement to check if it is set will prevent it from loading the URL with no variable.
The way we extract data via php from a form is like below
<html>
<head>
<title>Metar Test</title>
</head>
<body>
<form action="" method="POST">
<p>IACO Code: <input type="text" name="$2" value=""></p>
<input type="submit" name="submit" value="Submit">
</form>
<?php $html=file_get_contents("http://www.metar.mysite.net/metar?id=$_POST['$2']")?>
<?php echo $_POST ["$html"];?>
I'm trying to figure out what's going wrong here. I'm trying to post a question number to the page, so as you answer questions it increments up. For some reason I can't get it to post, the only way I got it to work was when I include var_dump($q_num); after the part where I increment the $q_num variable.
I'm assuming this is something very simple but I'm not sure what it is. Any help would be appreciated, thanks!
I know I should sanitize the input, and I've tried a FILTER
<?php
include('inc/quiz.php');
session_start();
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Math Quiz: Addition</title>
<link rel="stylesheet" href="css/normalize.css">
<link rel="stylesheet" href="css/styles.css">
</head>
<body>
<?php
if (isset($_POST['page'])){
$q_num = (int)$_POST['page'];
} else {
$q_num = 1;
}
$p_num = 10;
?>
<?php var_dump($q_num);?>
<div class="container">
<div id="quiz-box">
<p class="breadcrumbs">Question #<?= $q_num;?> of <?= $p_num;?></p>
<p class="quiz">What is <?php
?> </p>
<form action="index.php" method="POST">
<input type="hidden" name="page" value="<?php ($q_num+1);?>" />
<input type="submit" class="btn" name="answer" value="135" />
<input type="submit" class="btn" name="answer" value="125" />

I am trying to catch some text from the textbox, to save it in a variable and then post it on my browser if I click the submit button. My code is this:
<?php
$var1=$_POST['text1'];
$var2=$_POST['display'];
if(isset($var2)){
var_dump( $var1);
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title></title>
</head>
<body>
<input type="text" value="gdf" name="text1" id="text1" /><br /><br />
<input type="submit" id="display" name="display"><br /><br />
</body>
</html>
I don't know what is wrong. The code on rextester
For starters you need to implement a form on you HTML page and set the action to a new .php page.
<form action='display.php' method='post'>
*your input fields go here*
Now create a new php page (in this case display.php)
Declare the variables as you did....
$var1=$_POST['text1'];
$var2=$_POST['display'];
if(isset($var2)){
var_dump( $var1);
then you can simply echo each variable accordingly...
Final Result
HTML PAGE:
<form action='result.php' method='post'>
<input type="text" value="gdf" name="text1" id="text1" /><br /><br />
<input type="submit" id="display" name="display"><br /><br />
</form>
result.php
<?php
$var1 = $_POST['text1']; // create variables of your form elements
$var2 = $_POST['display'];
echo '$var1 . ' ' . $display . '.';
?>
Basically the php page is saying get text1 and display from the form (names) and create variables of them...
Then echo (print) these variables on the screen. (in plain english xD)
p.s
Your rextester isn't working because you haven't specified a form.
You need to setup the FORM tags so they have the correct attributes for POST. Try:
<html lang="en">
<head>
<meta charset="utf-8" />
<title></title>
</head>
<body>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
<input type="text" value="gdf" name="text1" id="text1" /><br /><br />
<input type="submit" id="display" name="display"><br /><br />
</form>
</body>
</html>
You need to use a form, otherwise you aren't posting anything.
Something like:
form.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title></title>
</head>
<body>
<form method="post" action="yourphpfile.php">
<input type="text" value="gdf" name="text1" id="text1" /><br /><br />
<input type="text" value="display" name="display" id="display" /><br /><br />
<input type="submit" value="submit"><br /><br />
</form>
</body>
</html>
yourphpfile.php
<?php
if(!empty($_POST['text1']) and !empty($_POST['display'])){
$var1=$_POST['text1'];
$var2=$_POST['display'];
echo "$var1 $var2";
}
?>
Check this complete example
To display text box and button on clicking submit button
<form>
<input type="submit" value="OK" name="btn_name"/><br />
<?php
if(isset($_GET['btn_name']))
{
echo "<input type=text name=txt_userinput />";
echo "<input type=submit value=Area name='btn_calculate'/>";
}
?>
</form>
I'm having problems passing data from a form, I can't figure out where I've gone wrong. I have modeled my page on one that works but mine does not function.
I want to check I have the general structure right. I have stripped it right down and it still wont work.
<?php
define('INCLUDE_CHECK',true);
include 'php/functions.php';
error_reporting(E_ALL);
ini_set('display_errors',1);
logThis('ready!');
if (isset($_POST['submit'])) {
logThis('success');
}
?>
<html>
<head>
</head>
<body>
<form method="post" action="">
<input type="submit" name="submit" id="submit" value="Submit" />
</form>
</body>
</html>
This is the whole page now, I have commented everything else out.
logThis() works i get the 'ready!' in the log but no 'success' message when ever i press the submit button.
Sorry for my bad english!
In PHP, $_POST expect the name of input field, not the id.
So you need to set names to your fields:
<input type="hidden" id="villainClass" name="villainClass" value="" />
<input type="hidden" id="heroClass" name="heroClass" value="" />
Modify your HTML code
You can get posted data only by the name of input field
<?php
if(isset($_POST["username"]))
{
$username = $_POST["username"];
echo $username;
}
?>
<html>
<head>
</head>
<body>
<form method="post" action="">
<input type="text" name="username"/>
<input type="submit" name="submit" id="submit" value="Submit" />
</form>
</body>
</html>
index.php
<html>
<head>
<script type="text/javascript">
function submitForms()
{
document.forms["form-1"].submit();
document.forms["form-2"].submit();
}
</script>
</head>
<body>
<form method="POST" action="form.php" id='form-1'>
<input type="text" name="txt1" />
</form>
<form method="POST" action="form.php" id='form-2'>
<input type="text" name="txt2" />
</form>
<input type="button" value="Click Me!" onclick="submitForms();" />
</body>
</html>
form.php
<?php
echo $_POST['txt1'];
echo $_POST['txt2'];
?>
Above is my code and when i submit both forms then both text-fields with their value it does not shoe me both text-field values.It only shoe me second text-field value.Please help me quickly.
I think because you try to get the params after sumbit two forms. You have sent the two forms at once and the second has stepped to the first, so the result is the return of the second form.
I think this will be better:
<html>
<head>
</head>
<body>
<form method="POST" action="form.php">
<input type="text" name="txt1" />
<input type="text" name="txt2" />
<input type="submit" value="Click Me!" />
</form>
</body>
</html>
<?php
echo $_POST['txt1'];
echo $_POST['txt2'];
?>
