wildteen88 Posted September 5, 2006 Share Posted September 5, 2006 Your intentions are completly wrong. PHP runs on the server and generates the output back to the browser. You canno do this:[code]input name="imageField" type="image" ... onClick="<?php $Username = $_POST['txtLogInUserName']; ?>" >[/code]As befoe the HTML is even shown PHP would have created the username var and assign it it the value of whats in $_POST['txtLogInUserName'] variable.What you'll want to do is something like this:[code=php:0]<?php//check that the form has been submitted:if(isset($_POST['imageField_x'])){ // form has been submitted! // now we set up the username variable: $Username = $_POST['txtLogInUserName'] // Welcome the user: echo 'Welcome <i>' . $Username . '</i>, How are you today?<br /><br />';}else{ // Foprm hasnt been submitted so we'll tell them to: echo "Please fill out the form below, click submit when done<br /><br />";}?><div id="lyrLogin" style="position:absolute; left:578px; top:60px; width:166px; height:45px; z-index:20; visibility: visible;"> <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" name="frmLogIn" id="frmLogIn"> <p align="left"> <input name="txtLogInUserName" type="text" id="txtLogInUserName" /> </p> <p> <input name="imageField" type="image" src="login_button_up.gif" width="105" height="36" border="0" value="Submit" /> </p> </form></div>[/code]When you first go to the page, [i]Please fill out the form below, click submit when done[/i] will be displayed above the form. But when you fill in the form and press sumit, you'll get a welcome message with the username you put in the txtLogInUserName text field.

wildteen88 Posted September 6, 2006 Share Posted September 6, 2006 Oops missed out the semi-colon after this:Change:$Username = $_POST['txtLogInUserName']to this:$Username = $_POST['txtLogInUserName']; Quote Link to comment https://forums.phpfreaks.com/topic/19749-i-guess-very-simple-declaring-variables-from-a-user-input/#findComment-87200 Share on other sites More sharing options...
