SORRY FRIENDS FOR THIS QUESTION, I TESTED THE SAME CODE IN REAL TIME SERVER. IT WORKED FINE, BUT WHEN THE CODE RETURN IN PHPSTORM IT NOT WORKED.
(don't know exactly what the reason )
First.php
<form action="second.php" method="post" >
Name: <input type="text" name="name" >
<input type="submit">
</form>
second.php
<?php
if(isset($_POST["name"])){
$username = $_POST["name"];
echo $username;
}else
{
echo "null value";
}
?>
Here i am getting null value.
dont know what the reson.
but i simple testing this will GET (where method="get")
and
second.php is
<?php
echo $_GET["name"];
?>
it worked well.
Try this:
HTML
<form action="second.php" method="post" >
Name: <input type="text" name="name" >
<input type="submit">
PHP
<?php
if($_SERVER['REQUEST_METHOD'] == "POST")
{
$username = $_POST["name"];
echo $username;
}else
{
echo "null value";
}
?>

<?php
Function runSearch($name)
{
If(isset($_POST['submit']))
{
$name = $_POST['name'];
echo "Results for " .$name;
}
}
?>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
Search String: <input type="text" name="name"><br>
<input type="submit" name="submit" value="Submit"><br>
</form>
This code is suppose to display what is entered into the Search String text box. When I don't use a function it works fine. But as soon as I place the code into the function runSearch there is no output. I'm new to php can an argument be sent to a php function and then displayed on the screen?
you need to call your function, otherwise nothing will happen. Also you need to removed the $name-parameter:
<?php
function runSearch()
{
if(isset($_POST['submit']))
{
$name = $_POST['name'];
echo "Results for " .$name;
}
}
runSearch();
?>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
Search String: <input type="text" name="name"><br>
<input type="submit" name="submit" value="Submit"><br>
</form>
i want to do somthing like:
1.php:
<html>
<form action=1.php method=POST enctype="multipart/form-data">
Choose a user name:<input type="text" name="username">
<input type="submit" value="Save and Proceed">
</html>
<?php
if(isset($_POST['username']))
{
$name=$_POST['username'];
echo $name;
if($name=='azra')
{
?>
<html>
<form method="POST" action="1.php" enctype="multipart/form-data"></br>
enter age:</font> <input type="text" name="age">
<input type="submit" value="done">
</form>
</html>
<?php
f( isset($_POST['age']))
{
$age=$_POST['age'];
echo $age;
if($age==25)
{
echo "your age is ". $age;
echo"you are eligible";
}
}
}
}
?>
After the second form is submitted i do not want the script 1.php to run from the start but i want it to run the code following the form which is echoing the age only.
i do not want to go putting the later code in second script and accessing the variable of first script through making them session variables.please help. thankyou in advance
Change your condition to this
if ((isset($_POST['username'])) && ($_POST['submit'] == 'Save and Proceed')) {
}
this is the code i changed:
<html>
<form method="POST" action="2.php" enctype="multipart/form-data"></br>
Choose a user name:</font> <input type="text" name="username">
<input type="submit" value="Save and Proceed">
</form>
</html>
<?php
if(isset($_POST['username']) && ($_POST['submit'] == 'Save and Proceed'))
{
$name=$_POST['username'];
echo $name;
if($name=='azra')
{
?>
<html>
<form method="POST" action="2.php" enctype="multipart/form-data"></br>
enter age:</font> <input type="text" name="age">
<input type="submit" value="done">
</form>
</html>
<?php
if( isset($_POST['age']) && ($_POST['submit'] == 'done'))
{
$age=$_POST['age'];
echo $age;
if($age==25)
{
echo "your name is" .$name;
echo "your age is ". $age;
echo"you are eligible";
}
}
}
}
?>
I'd like to know if it is possible to manage error if in the form, action is set to another script.
ajoutDevis.php
<FORM name='devis' method='POST' action='ajoutDevisScript.php' id='form'>
<label for="client">Client</label>
<input type='text' id='client' name='client'>
<span class="error">* <?php echo $clientErr;?></span>
</FORM>
ajoutDevisScript.php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if(empty($_POST['client'])) {
$clientErr = "ERROR";
} else $client = $_POST['client'];
So, is it possible to display my error in the span if the input is empty ? Or there is no way doing it with an other script as action ?
Thanks!
session_start();
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if(empty($_POST['client'])) {
$clientErr = "ERROR";
$_SESSION['error] = $clentErr;
header('location:ajoutDevis.php');
} else $client = $_POST['client'];
In your ajoutDevis.php file
session_start();
$clientErr = ($_SESSION['error']!='')?$_SESSION['error']:'';
<FORM name='devis' method='POST' action='ajoutDevisScript.php' id='form'>
<label for="client">Client</label>
<input type='text' id='client' name='client'>
<span class="error">* <?php echo $clientErr;?></span>
</FORM>
You need to do the following:
Add the form code as well on the ajoutDevisScript.php page at the bottom of page.
<?php if(!empty($clientErr)) { ?>
<FORM name='devis' method='POST' action='ajoutDevisScript.php' id='form'>
<label for="client">Client</label>
<input type='text' id='client' name='client'>
<span class="error">* <?php echo $clientErr;?></span>
</FORM>
<?php } ?>
This will check if there is any error in error variable it will display the form on same page with error.
Yes, it is possibile with $_SESSION variables to store values during the session and header() function to redirect user from the second script back to the first.
Supposing both files are in the root directory, ajoutDevis.php:
<?php
session_start();
?>
<FORM name='devis' method='POST' action='ajoutDevisScript.php' id='form'>
<label for="client">Client</label>
<input type='text' id='client' name='client'>
<?php if (isset($_SESSION['clientErr'])) : ?>
<span class="error">* <?php echo $_SESSION['clientErr'] ?></span>
<?php endif; ?>
</FORM>
and ajoutDevisScript.php:
<?php
session_start();
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if(empty($_POST['client'])) {
$_SESSION['clientErr'] = "ERROR";
header('Location: ajoutDevis.php');
} else {
$client = $_POST['client'];
}
}
?>
I would suggest you to print the span only if you need to. I would also suggest you to check your brackets to avoid PHP errors.
I'm building a form, and I want that all the inserted values will be kept, in case of form submit failure. This is my code:
<?php
$error = "";
$name = "";
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$name = $_POST["name"];
// Verify $_POST['name'] greater than 4 chars
if ( strlen($name) < 4 ){
$error= 'Name too short!';
}
}
?>
<html>
<head>
</head>
<body>
<form method="post" action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']); ?>" name="myForm" id="idForm">
<input type="text" placeholder="Name" id="name" name="name" value=""/>
<input type="submit" value="submit"/>
</form>
<?php
echo "<h2>Input:</h2>";
echo $name;
if($error) {
// No Update AND refresh page with $name in text field
echo "<br/>" . $error;
} else {
// Update name in DB
}
?>
</body>
</html>
I would like that name field keeps the inserted input text, after submit. I tried to do with php code in input value but doesn't work. Any ideas?
Solved. This is the solution that I was looking for.
I added in value tag of input the following:
<?php if (isset($_POST['name'])) echo $_POST['name']; ?>
Therefore input field would look like:
<input type="text" placeholder="Name" id="name" name="name" value="<?php if (isset($_POST['name'])) echo $_POST['name']; ?>"/>
Thanks for your responses, helped me.
<?php
$error = "";
$name = isset($_POST["name"])?$_POST["name"]:""; //Added condition
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$name = $_POST["name"];
// Verify $_POST['name'] greater than 4 chars
if ( strlen($name) < 4 ){
$error= 'Name too short!';
}
}
?>
<html>
<head>
</head>
<body>
<form method="post" action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']); ?>" name="myForm" id="idForm">
<input type="text" placeholder="Name" id="name" name="name" value="<?php echo $name; ?>"/>
<input type="submit" value="submit"/>
</form>
<?php
echo "<h2>Input:</h2>";
echo $name;
if($error) {
// No Update AND refresh page with $name in text field
echo "<br/>" . $error;
} else {
// Update name in DB
}
?>
</body>
</html>
You can just echo $_POST['name'] in the value attribute of the input.
Make sure you check POST values to avoid XSS.
I also put up the update DB function, as you don't need to show the form to the user if the name in longer the 4 chars!
<?php
$error = "";
$name = "";
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if (isset($_POST['name'])){ //change name content only if the post value is set!
$name = filter_input (INPUT_POST, 'name', FILTER_SANITIZE_STRING); //filter value
}
// Verify $_POST['name'] greater than 4 chars
if ( strlen($name) < 4 ){
$error= 'Name too short!';
} else {
// Update name in DB
// Redirect
}
}
?>
<html>
<head>
</head>
<body>
<form method="post" action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']); ?>" name="myForm" id="idForm">
<input type="text" placeholder="Name" id="name" name="name" value="<?php echo $name; ?>"/>
<input type="submit" value="submit"/>
</form>
<?php
echo "<h2>Input:</h2>";
echo $name;
if($error) {
// No Update AND refresh page with $name in text field
echo "<br/>" . $error;
};
?>
</body>
</html>
If you want to keep all values/inputs for further use you could achieve that with php session values.
Besides - you should use $_SERVER['SCRIPT_NAME'] instead of $_SERVER['PHP_SELF']

I have this piece of code and I want to show result in the third input box not in the input box and hole page and i want to know if i can a $_GET['$vairbles'] whiten functions
NOTE : I’m beginner in php programming
Here is my code :
<?php
$email = "mail#somedomain.com";
if (isset($_GET['txt1']) and isset($_GET['txt2'])) if (!empty($_GET['txt1']) and!empty($_GET['txt2'])) {
$tex1 = $_GET['txt1'];
$tex2 = $_GET['txt2'];
echo "They are all filled.<br>";
} else {
echo "Please fill in first and second Fields";
}
shwor();
Function shwor() {
global $email;
global $tex1;
global $tex2;
$len1 = strlen($tex1);
$len2 = strlen($tex2);
if ($len1 and $len2 > 0) if ($tex1 == $tex2) echo "matched ";
else echo "Does not match";
}
?>
<form action:"email.php" method="GET">
<input 1 type="text" name="txt1"><br><br>
<input 2 type="text" name="txt2"><br><br>
<input 3 type="text" name="Result" value = "<?php shwor();?>"><br><br>
<input type="submit" value="Check matches"><br>
</form>
everything works, just misspelled in this line:
<form action:"email.php" method="GET">
should be:
<form action="email.php" method="GET">
..and remember to name your file email.php that the data will be sent to the file itself ;-)
