PHP - Simple Syntaxing Issue With $_get[variable]
The code below works
echo '<script language="javascript">'; echo 'top.location.href = "/breaking-news/bsnewsstorygoeshere/";'; echo '</script>'; this also works echo '<script language="javascript">'; echo 'top.location.href = "http://anywebsite.com";'; echo '</script>'; the problem, is I have a URL listed in a url variable that can be retreived via $_GET['url'] my question is how to get that variable into the above code? I've tried echo '<script language="javascript">'; echo "top.location.href = \"$_GET['url']\";"; echo '</script>'; but that doesnt seem to work, can anyone advise?

This code: <?php include 'header.php'; $tourn = $_GET['extourn']; echo "first ".$tourn."<br />"; if($tourn=0){ echo "tourn1 is ".$tourn."<br />"; } else{ echo "tourn2 is ".$tourn."<br />"; } ?> returns this: Quote first 4 tourn2 is 0 While tourn2 should return 4 as well. I have tried a million different versions, including switches and everything and just can't understand it. Please help! Hi I have written a simple bit of code, i used to code php a little and have just decided to start coding php again but for the life of me can't work out why this isn't working, so if someone could help this would be great. address www.mysite.co.uk/index.php?vid=video2 <php if (isset($_GET['vid'])){ $video=$_GET['vid']; }else{ $video="video1"; } when i echo $video i only get video=1 having a problem using get variables to include certain pages. I have a management script for a news feed that uses get variables to display certain parts of the script. here is the template/ main part of the script <?php session_start(); require_once("vars.php"); $username = $_SESSION['username']; $is_admin = $_SESSION['is_admin']; $referer = $_SERVER['HTTP_REFERER']; //check to see if user is logged in and is an administrator if((isset($_SESSION['username'])) && ($_SESSION['is_admin'] == 1)){ //if all session variables are set, display admin panel ?> <html> <head> <title>Administration</title> <link rel="stylesheet" type="text/css" href="/cameo/css/admin.css" media="screen" /> </head> <body> <table cellspacing="0" cellpadding="3" class="layout"> <tr> <td colspan="2"><h3>Administration</h3></td> </tr> <tr> <td valign="top"> <a href="index.php?pg=news">Manage News Feed</a> </td> <td> <?php $id = $_GET['pg']; switch($id){ case news: include("manage_news.php"); case editpost: include('edit_post.php'); break; } ?> </td> </tr> </table> </body> </html> <?php } else { echo("You do not have permission to view this page. <br />"); echo("<a href=\"".$referer."\">Go Back</a>"); } ?> and heres the edit post page that the script refers to <?php require_once("vars.php"); $id = $_GET['id']; $query = "SELECT * FROM news_feed WHERE id=".$id; $result = mysqli_query($dbc,$query); $row = mysqli_fetch_array($result); ?> <form method="post" action="update.php"> <textarea><?php echo $row['post_body']; ?></textarea> </form> now, for some reason, the edit post form is showing up under the main news feed listing, even though the get id does not match the one in the switch statement. thanks in advance for any help Hello! I was wondering if this could be done... I want to take a variable, and insert it into a URL for a $_GET on a different page? Basically Its a member website, and I want the admin to be able to "accept" or "deny" the application... So i have a page that displays all the applications, and I want it to take him to a different page with all the user's information in detail. Right now it only displays their name, but when the admin presses the link, it takes them to a more detailed page about the applicant, where they can then "accept" or "deny" the application.... Here is what i got so far... Code: [Select] $character_name = "Nightmareinhell"; <a href="admin_evaluate.php?name=$character_name">$character_name</a> Here is the error I get from the code above Quote Parse error: syntax error, unexpected T_STRING in C:\wamp\www\admin_acceptapply.php Thanks to any help!!!! Hi, I'm using $_GET to pass form data to a URL - http://localhost/projects/phpget/test.php?Q7=Dave&Q8=Smith&Q9=123+Road&Q10=ls11sl&Q2=dave%40hotmail.com&Q4=71&day=19&month=01&year=1995&Q263=3127&Q262=3126&x=99&y=24 All the form fields are named Qx and all are ok apart from dob. I've been trying to get the dob to be passed as dd-mm-yyyy with name of Q5, so in above example would be: http://localhost/projects/phpget/test.php?Q7=Dave&Q8=Smith&Q9=123+Road&Q10=ls11sl&Q2=dave%40hotmail.com&Q4=71&Q5=19-01-1995&Q263=3127&Q262=3126&x=99&y=24 I cannot name all 3 fields (date, month, year) as Q5 si i'm guessing that the 3 values need to be assinged to Q5 before the form is submitted??

I have used error_reporting(-1); but that is not coming up with any errors. Could anyone help please. Its probably so simple, but my mind is drawing a blank When i execute the following code, it works and retrieves the record info i am looking for for the appropriate record, 2155015898: $adgrouppass = 2155015898; $selector->adGroupIds = array($adgrouppass); However, when i try to get the adgroup variable from my url, which is where it is located, it doesn't work: $adgroup = trim($_GET['adgroup']); $adgrouppass = $adgroup; $selector->adGroupIds = array($adgrouppass); yet, in trying to fix it, if i echo the above variable, it says it is correct, which is 2155015898. Not sure if the $adgrouppass needs to be a string or variable to get it to pass it correctly. Can anyone help? <?php $foo = 5; $too = 7; ${"foo"}++; ${"too"}++; echo $foo; echo '<br />' . $too; $my_var_name = "foo"; ${$my_var_name}++; echo $foo; ?> I understand the part that $my_var_name is going to increment $foo. But I don't understand that when we used ${"foo"} we did not add the $ sign with it. But when we use ${$my_var_name} we have to add another $ sign. why is that?

Hello, I don't have any php knowledge and am having a hard time trying to implement the following: - a drupal node is getting a numeric parameter with the URL in the following form "http://the.url/?X=123" - what I want is for the script to check if the value has been passed with the URL, then use it in a form... if the entered URL was "http://the.url" without the X variable, then use a default value of 321. <?php $_GET['X']; if (isset($X)) { print $X ; } else print "321" ?> Thanks in advance for your help. I am trying to recursively pull records from a database to write to a csv. There are three test rows of data in my table (and no not including the table headers). The only issue is i can’t seem to get my for loop to display all the records – it only displays the last 2 rows so i’m very confused. Anyone suggest why this isn’t working? Code: [Select] $num_rows = mysql_num_rows($export); for ($i=0; $i <= $num_rows; $i++ ) { $row = mysql_fetch_row($export); echo $row[1] . $row[2] . $row[3] . $row[4] . $row[5] . $row[6] ."<br/>"; echo $i; } Incidentally the query is just a fetch all from datasbase. Anyone see where i'm going wrong? Thanks, drongo I have this simple piece of code. I am using GET[] to retrieve the catID from URL, then match it and set a backgorund image, some backgorund images can change per catID variable. When selected or clicked on. It is not working, it is producing the catId in ech $_Get[], but not matching it with $filename to set correct Image. Ex. Browser catID may == 1, it code displays catid = 1, file name = deals_2.jpg.

All the errors are sent to a form.php, this then sends the error message back to the current page. Here is the code I am using to retrieve the error message: if($form->error = ("user")){ echo $form->error("user"); } if($form->error = ("pass")){ echo $form->error("pass"); } Which works fine, but I only want ONE error message to be displayed at a time. This IS what I want: There are two fields, user, and password. If the user fails to enter anything into both, only one error message will appear "Please enter your username" (which is what the form.php does). When the user fills in the username, but fails to fill in the password then it works, only one error message appears (as there is only one error to send) When the user fills in the password, but fails to fill in the username it also works, only one error message appears. Its just when the user fails to fill in either, it prints both error messages when I only want it to print the 'user' error message. Please help, Thanks I am stuck on trying to get the form to repopulate after a failed validation. The real form involves REST calls and such but I trimmed the code back to this issue. I think I need to declare the variables differently. I also tried to use the variables in the PHP script to refill the form with the original form entries. I have tried numerous ways of getting the variables to repopulate but could never get it to work consistently (such as declaring global variables. Here is the form code: Code: [Select] <div> <a name="error_field"></a> <?php if($_GET['error']): ?> <div style="padding:10px;border:1px solid;color:#C70C0C;"><?php echo $_GET['error'] ?></div> <?php endif; ?> <div> <form method="post" action="process2.php"> <fieldset name="Group1"> <legend>Account Registration</legend> <div id="field"><label id="Firstname">First Name:</label></div> <div id="input"><input name="Firstname" id="Firstname" type="text" value="<?php $_POST['Firstname']?>"/></div> <div id="field"><label id="Lastname">Last Name:</label></div> <div id="input"><input name="Lastname" id="Lastname" type="text" value="<?php $_POST['Lastname']?>"/></div> <div id="field"><label id="Username">E-Mail Username):</label></div> <div id="input"><input name="Username" type="text" value="<?= $_POST['Username']?>"/></div> <div id="field"><label id="Password">Password:</label></div> <div id="input"><input name="Password" type="password" /></div> <div class="center" style="margin-top:15px;margin-bottom:15px"> <input name="Submitx" type="submit" value="submit" /> <input name="Reset1" type="reset" value="reset" /> </div> </fieldset></form> </div> </div> and here is the PHP which I have on a different page Code: [Select] <?php $new_user_username = check_input($_POST['Username'], "Enter your e-mail"); $new_user_password = check_input($_POST['Password'], "Enter your password"); $new_user_first_name = check_input($_POST['Firstname'], "Enter your first name"); $new_user_last_name = check_input($_POST['Lastname'], "Enter your last name"); /* If e-mail is not valid show error message */ if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/", $new_user_username)) { show_error("E-mail address not valid"); } else{ header('Location: TY.php'); } function check_input($data, $problem='') { $data = trim($data); $data = stripslashes($data); $data = htmlspecialchars($data); if ($problem && strlen($data) == 0) { show_error($problem); } return $data; } function show_error($myError) { header('Location: tp1.php?error=' . $myError); exit(); } ?> Thanks in advance for any help. Hi there, I am working on a PHP web form and I have a very simple situation I guess, I have a variable named: $MyVal When I do print_r($MyVal); To see whats inside, I get: SimpleXMLElement Object ( [0] => 8.23 ) Now I am assigning this variable into a session variable so that I can do calculations with it. So I assign: $_SESSION['MySesVal'] = $MyVal; But after assigning to session variable, when I do my calculations: $finalValue = $_SESSION['MySesVal'] * 4; I get 0. So is it because the actual $MyVal variable has some XML stuff as: SimpleXMLElement Object ( [0] => 8.23 ) So what is the right way to properly assign $MyVal variable to a session variable to do calculations. Please reply. All comments and feedbacks are always welcome. Thank you! |
