Printing text box value on page in PHP
I am new to PHP (in-fact I am learning it). I am开发者_JAVA技巧 trying to get the value of textbox defined in HTML and print it on HTML page through PHP code. I am able to send the value of textbox to another page using form post and getting it using $_POST['name'] on other page.
I am not able to print the value of textbox on same page.
Here is my code:
<html>
<head>
<?php
function myfunction()
{
printf($_POST['fname']);
}
?>
</head>
<body>
Name: <input type="text" name="fname" />
<input type="button" onClick="myfunction()" value="Click" />
</body>
</html>
First of all it's not required to write php function within <head> tags. Second,
you can't POST data without <form> tags. try this
<?php
if(isset($_POST['submit']) && $_POST['submit']=='Submit'){
$name=$_POST['fname'];
echo $name;
}
else {
?>
<html>
<head>
</head>
<body>
<form method="POST" action="<?=$_SERVER["PHP_SELF"]?>">
Name: <input type="text" name="fname" />
<input type="submit" name="submit" value="Submit"/>
</form>
</body>
</html>
<?php } ?>
you can not call PHP function by button's click event...
if you want to print on same page then you can do by below code..
<html>
<?php
if(count($_POST)>0){
echo $_POST['fname'];
}
?>
<body>
<form method='post'>
Name: <input type="text" name="fname" />
<input type="submit" value="Click" />
</form>
</body>
</html>
hope you will get what you want by my answer..
