javascript - I can't pass a variable from my jQuery code to my PHP code -
i'm trying pass variable jquery code html/php code using ajax , post, error message "notice: undefined index: testdata in c:\xampp\htdocs\teszt\test1.php on line 9".
i'm using xampp, i'm running code in localhost, i'm using mozilla firefox , here's html/php code (test1.php):
<!doctype html> <html lang="hu"> <head> <title>test</title> <meta http-equiv="content-type" content="text/html;charset=utf-8"> </head> <body> <?php echo "<p class='testparagraph'>" . $_post['testdata'] . "</p>";?> <script src = "http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script> <script type="text/javascript" src="http://code.jquery.com/jquery-1.8.0.min.js"></script> <script type="text/javascript" src="script.js"></script> </body> </html> and here's jquery code (script1.js):
$(document).ready(function() { var temporaryvariable = "temporary variable"; $.ajax({ type: "post", url: "test1.php", data: { testdata:"2" }, success: function (result) { alert('success'); } }).done(function() { $('.testparagraph').addclass( temporaryvariable ); }); }); what tried changing far (but didn't work of course):
test1.php:
- charset
iso-8859-2 getinstead ofpostin both codes- commenting out
scripttag includes
script1.js:
- commenting out
$(document).ready(function() {...lines - in
data:tried changing quote symbols'"or no quote symbols @ all - commenting out
success: function...line , 2 lines below it
also, when run php code, p tag gets temporaryvariable class jquery code.
still, error message written above. appreciate get.
change test1.php to:
<!doctype html> <html lang="hu"> <head> <title>test</title> <meta http-equiv="content-type" content="text/html;charset=utf-8"> </head> <body> <p id='testparagraph'> </p> <!-- receive value jquery not php. --> <script src = "http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script> <script type="text/javascript" src="http://code.jquery.com/jquery-1.8.0.min.js"></script> <script type="text/javascript" src="script.js"></script> </body> </html> and script1.js to:
$(document).ready(function() { var temporaryvariable = "temporary variable"; $.ajax({ type: "post", url: "test1.php", data: { testdata:"2" }, success: function (result) { alert('success'); } }).done(function() { $('#testparagraph').html(temporaryvariable); //the value inserted paragraph. }); }); hope works you.
