PHP - How To Keep <?php Echo $_get['x']; ?> As Some Variables?
Hello,
I just wanna know if any such commands are available in php for making a variable as such like - $variable = " blah blah .. . . . index.php?X=<?php echo $_GET['x']; ?>..........blah"; thank you Similar TutorialsHi all - I'm trying to echo $_GET something from the URL, and display a short message to the user if the echo $_GET fails - but I'm new to PHP and the code I've whipped up doesn't work. It always displays the message even if the information is present in the url and the $_GET should work. Here's the code I've got:
<h3>
<?php
$qset = strpos($_SERVER['SCRIPT_NAME'], 'qtitle');
if ($qset === false) {
echo "You haven't added any questions yet.";
} else {
echo $_GET['qtitle'];
}
?>
</h3>
The URL will contain "qtitle=(something)" if they've filled out a form on the prior page.
Can someone tell me what I'm doing wrong? I have a feeling I've overcomplicated things...
Thanks again!
I have a file called myfile.html and it includes the following line: Code: [Select] <!--#include virtual="/output.php" --> The SSI statement works great, but I want more... I would like to be able to link to myfile.html?var=val and use the var string in the php file. However $_GET[var] equals nothing when I try this Is this not possible? I have this code: Code: [Select] <?php $item_name = urlencode('product name'); $payment_amount = urlencode('20.00'); $payer_email = urlencode('me@email.com'); $getvars = "?item_name=$item_name&payment_amount=$payment_amount&payer_email=$payer_email"; include "http://www.mysite.com/ipn.php$getvars"; ?> It only seems to be passing $item_name, the other 2 variables come up as being set, but are empty. I am building a member-based website, and I've got a bunch of buttons that lead from page to page. The links for these buttons are generated based on user ID and subsequent pages receive this variable as well. So, if you hover over the buttons, you get a link like this: http://www.mysite.com?id=423 How can I hide the last part? The '?id=423'? I must use this format of variable, and cannot resort to session variables. Is there a way to hide this portion of the links?? Hi all. I have a question and don't know if it belongs in the PHP section or the Javascript section so I apologize in advance if I am in the wrong place. Basically what I am trying to do is change a URL with the following variables Code: [Select] index.php?id=16&?pid=23-P27-16&cid=1324353245 to something more secure....like Code: [Select] index.php I think doing it this way would add an extra layer of security to my website. If this is not possible, is there a way I can track whether or not a user attempted to edit something in the URL. For example, if the cid=13243543 and they go in a change it to 13243654 instead, can I have PHP check that? I have a great deal of security already, but I think this would truly be the highest layer, completely controlling what happens in the user's address bar. As always, thanks in advance! Bl4ck Maj1k I have a php search page that takes form data to create its queries, then reload the original search page. The form is long, so there are numerous $_POST's to convert to variables for use in the query. I've looked at "extract" and a few other code snippets. But it's a form and I don't want any security issues. I'm hoping there's a "foreach" solution, but I'm a beginner. What's a proper way to to simplify this: $s1 = $_POST["s1"]; $s2 = $_POST["s2"]; $s3 = $_POST["s3"]; $s4 = $_POST["s4"]; $s5 = $_POST["s5"]; $s6 = $_POST["s6"]; $s7 = $_POST["s7"]; $s8 = $_POST["s8"]; $s9 = $_POST["s9"]; $s10 = $_POST["s10"]; $s11 = $_POST["s11"]; $s12 = $_POST["s12"]; What I would like to find out is how I can echo out all the variables that are in use in the visitors visit. And have these echoed on the page. (for error checking purposes) some of my variables i.e. $username or $email and a few others are being cleared of its content and I can not find any problems searching all the files for the variable name and checking the lines but think that some other variable is in turn causing theproblems. so wanting to find a way to place an echo line that shows all the variables and then have the next line exit; and just move these two new lines around my scripts to find out where the problems might be. Hello all, I'm passing variables through a URL. This will work: echo $v4; But neither of these will: echo "<a href='test.php?v4=$v4'>Places</a>"; echo "<a href='test.php?v4=".$v4."> Places</a>"; It WILL work if I hardcode v4, like so: echo "<a href='test.php?v4=Utah'>Places</a>"; But that's useless to me, as I don't want to have to write 50 If statements for every database entry. Does anyone know how to fix this? Thanks! Hi, I want to send the following variable using the $_GET function: I need to echo out some string variables in a form. I also want to add some validation for Name, email etc. I think I have the code right or close, but I can an error on the index.php page which is. "Fatal error: Call to undefined function form_row_class() in index.php on line 14" here is the code for the form <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>String Tester</title> <link rel="stylesheet" type="text/css" href="main.css"/> </head> <body> <div id="content"> <h1>String Tester</h1> <form action="submit.php" method="post"> <table> <tr class="<?php echo form_row_class("name") ?>" > <th><label for="first_name">Name</label></th> <td> <input name="first_name" id="first_name" type="text" value="<?php echo h($_POST['name']); ?>" /> <?php echo error_for('name') ?> </td> </tr> <tr class="<?php echo form_row_class("email") ?>"> <th><label for="email">Email Address</label></th> <td> <input name="email" id="email" type="text" value="<?php echo h($_POST['email']); ?>" /> <?php echo error_for('email') ?> </td> </tr> <tr> <th></th> <td><input type="submit" value="submit" /></td> </tr> </table> </form> <h2>Message:</h2> <?php echo "<table>"; echo "<tr><td>"; echo $name; echo "</td></tr>"; echo "<tr><td>"; echo $email; echo "</td></tr>"; echo "<tr><td>"; echo $phone; echo "</td></tr>"; echo "</table>"; ?> </div> </body> </html> and the submit portion <?php // If request is a form submission if($_SERVER['REQUEST_METHOD'] == 'POST'){ // Validation // Check first_name is non-blank if(0 === preg_match("/\S+/", $_POST['name'])){ $errors['name'] = "Please enter a name."; } // Check email is valid (enough) if(0 === preg_match("/.+@.+\..+/", $_POST['email'])){ $errors['email'] = "Please enter a valid email address."; } // validate a phone number if( !preg_match("/^([1]-)?[0-9]{3}-[0-9]{3}-[0-9]{4}$/i", $phone) ) { echo 'Please enter a valid phone number'; } // If no validation errors if(0 === count($errors)){ // Sanitize first, last, and email $name = mysql_real_escape_string($_POST['name']); $email= mysql_real_escape_string($_POST['email']); $email= mysql_real_escape_string($_POST['phone']); } // Helpers function form_row_class($name){ global $errors; return $errors[$name] ?

A few months ago, and a good amount of time before that, I had people telling me to use isset() instead of performing to see if the variable is empty, such as: !$_GET[''] I know the differences in the function and what they do, but when could isset() be used in a situation where it's better/more efficient then: !$_GET[''] I do use isset(), though. OK, have no idea what's going on... I've done this a million times... why wont this output!?? I must have a major brain meltdown and dont know it yet!!! Code: [Select] <?php // this echoes just fine: echo $_POST['testfield']; // but this wont echo: echo if (isset($_POST['testfield'])) { $_POST['testfield'] = $test; } echo $test; /// or even this DOESNT echo either!: $_POST['testfield'] = $test; echo $test; ?> Hi All, I'm trying to echo the response from an SLA query, the query works and returns the data when I test it on an SQL application.. but when I run it on my webpage it won't echo the result. Please help? <?php $mysqli = mysqli_connect("removed", "removed", "removed", "removed"); $sql = "SELECT posts.message FROM posts INNER JOIN threads ON posts.pid=threads.firstpost WHERE threads.firstpost='1'"; $result = mysqli_query($mysqli, $sql); echo {$result['message']}; ?> does anyone know how to decode this XML variable value into string values? I also need to know the oposite way: creating variable values into xml. I've tried several code examples but they did filter the requested data.

I am trying to make it so that the left side has the 10 most recent logs, then the right as the next 10. Any ideas? So I need to echo a row from my database with php, but where i need to echo is already inside an echo. This is my part of my code: $con = mysql_connect("$host","$username","$password"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("main", $con); $result = mysql_query("SELECT * FROM Vendor"); while($row = mysql_fetch_array($result)) { //I need to echo right here .................. but I get a blank page when I try this. Please Help. echo '<option value=$row['vendor_id']>'; echo $row['vendor_id']; echo '</option>'; } mysql_close($con); Result: A Blank page. Thanks in advance! I never really thought about it before, but recently I visited a site with a url like: www.example.com/?OR Which made me wonder how you would go about getting that keyname since it is without a value. Any ideas? Hello can any one help me with this question iv only just started to use the get function like <code> if (isset($_GET['pageID'])){ echo $row['content']; } </code> can any one if me info how to make it safe I have some javascript for a tabbed interface in index.php. The content of each tab is in content.php which uses $_GET to define which tab is selected. But i want to include queries based on variables from index.php how would i do this? here is the code for the tabbed interface: <script language="JavaScript" type="text/javascript" src="<?php echo SITE_ROOT; ?>/js/ahahLib.js"></script> <script language="JavaScript" type="text/javascript"> function makeactive(tab) { document.getElementById("tab1").className = ""; document.getElementById("tab2").className = ""; document.getElementById("tab3").className = ""; document.getElementById("tab"+tab).className = "active"; callAHAH('includes/content.php?content= '+tab, 'content', 'Loading...', 'Error'); } </script> <ul id="tabmenu" > <li onclick="makeactive(1)"> <a class="" id="tab1">Account Information</a> </li> <li onclick="makeactive(2)"> <a class="" id="tab2">Second Page</a> </li> <li onclick="makeactive(3)"> <a class="" id="tab3">Third Page</a> </li> </ul> <div id="content"></div> and the code in content.php if ($_GET['content'] == 1) { echo 'Content for Page 1'; } if ($_GET['content'] == 2) { echo 'Content for Page 2'; } if ($_GET['content'] == 3) { echo 'Content For Page 3'; } ive tried adding the variable $user_id to the content.php url as follows: callAHAH('includes/content.php?user=$user_id&content= '+tab, 'content', 'Loading...', 'Error'); } but that just brought up an error. I have javascript to load to my div the contents from php files something like this: QueryString is an addon javascript file loaded above so it works.. var get_id = $.QueryString["id"]; switch(get_id){ case 'page1': $('#div').load('php.php'); break; } on php.php when i try to get the $_GET['id']; which is obviously 'page1' it cant display it... i get nothing , i use switch in order to create dynamic div so i can click in my links and just load the divs content thanks. |
