PHP - Posting Variable In A Hidden Field.
Similar TutorialsI am having trouble sending information that was entered into a form, on the same page to the next page. I am sure i have done this a few years ago but cant find the code and cant find the answer online, hope someone can help me. My code is as follows: <form method="POST" action="https://.............. .asp "> <table> <tr> <td>Name: </td> <td><input type="text" name="clientname" /></td> </tr> <tr> <td>E-mail:</td> <td><input type="text" name="email" /></td> </tr> <tr> <td>Contact No:</td> <td><input type="text" name="telno" /></td> </tr> </table> <?php $udate = date("y-m-d H:i:s", strtotime ("+2 hour")); $uniquevalue = "$udate" . " " . "Simpay Pro"; echo $uniquevalue; ?> <br /> <input type="hidden" name="info1" value="<?php print $uniquevalue?>"> <input type="hidden" name="info2" value=$clientname> <input type="submit" value="Submit"> </form> So basically info1 is working i can see the value on the next page after its submitted, but info2 is the value of the input field. Is this possible to do it like this, or do i have to send it to another page and then to my last page that displays the values? I have one field which is set up as a Text field in my database. What I'm wanting is if the field is blank in the form to just leave the field alone in the database. I need it to be NULL. OR...is there a way to query a database to recognize a field is blank? I have a while loop that fetches data from the database and prints it out organized in a table. Now I want to implement a voting functionality, the problem I'm encountering is, once I've printed out a list of tables one table after other with the while loop I need to figure out a way to tell the query TO WHICH of those tables to ADD or SUBTRACT the vote. I thought of implement a hidden id field into the while loop of contributions, the id field would be fetched from the auto_increment field in the contribution table in the MySQL database. Since the id field is unique there can be no misunderstandings to which table to add the vote. My question how can I do exactly that? How can I add a hidden id field to the while loop with the table WHICH I then can pass along to the voting script. Here's the while loop: while ($row = mysqli_fetch_array($data)) { echo "<table padding='0' margin='0' class='knuffixTable'>"; echo "<tr><td width='65px' height='64px' class='avatar_bg' rowspan='2' colpan='2'><img src='$avatar_path' alt='avatar' /></td><td class='knuffix_username'><strong>" . $user_name; echo "</strong><br />" . $row['category'] . " | " . date('M d, Y', strtotime($row['contributed_date'])) . "</td></tr><tr><td>"; echo "<form action='' method='post'> <input type='submit' name='plusVote' value='Y' /> <input type='submit' name='minusVote' value='N' /> </form></td><td class='votes'>Y[ - ] | N[ - ]</td></tr>"; echo "<tr><td class='knuffix_name' colspan='3'><strong>" . htmlentities($row['name']) . "</strong><br /></td></tr>"; echo "<tr><td colspan='2' class='knuffix_contribution'><pre>" . $row['contribution'] . "</pre><br /></td></tr>"; echo "</table>"; } If I simply add $row['con_id'] it's obviously going to be echo'd out, what is the right practice to have it hidden? so I have this code: Code: [Select] <input type='checkbox' name='title8' value='$title8' /></td><td><strong>$title8</strong> <br /> $date8 <br />$ $price8<input type='hidden' name='price8' value='$price8'> how do I make is so that the hidden field is only going to submit if the checkbox is checked........ Hi all Basically, I have a form which when done will calculate a quote for turf for given areas. Basically each time the user specifies an area it goes into an array, and they can add as many as they want, but the problem seems to be once submitted and it arrives back into the program, it isn't decoding so the multidimensional array is lost. What am I doing wrong here? Full code below, thanks in advance Ste Code: [Select] <?php // Framework // Get the sections $sections_array = base64_decode(unserialize($_POST['sections'])); // Build the rest of the array foreach ($sections_array as $section) { $sections[] = base64_decode(unserialize($section)); } // Set the initial unit $units = $_POST['units']; // Do the new add if ($_POST['a'] == 'add_section') { // Add the new measure if ((is_numeric($_POST['width'])) && (is_numeric($_POST['length']))) { $sections[] = array('length' => $_POST['length'], 'width' => $_POST['width']); } } // Build the output foreach ($sections as $section) { $output .= '<strong>'.$section['width'].' wide</strong> x <strong>'.$section['length'].' long</strong><br />'; $sections_array = base64_encode(serialize($section)); } ?> <!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> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Untitled Document</title> <style type="text/css"> body,td,th { font-family: Verdana, Geneva, sans-serif; font-size: 11px; } body { margin-left: 0px; margin-top: 0px; margin-right: 0px; margin-bottom: 0px; } .wrap { text-align: center; height: 350px; width: 410px; padding: 0 10px; } </style> </head> <body> <div class="wrap"> <h2>Turf Calculator</h2> <p>To begin, enter the width and length of the first area of garden you wish to turf.

The $id variable is showing up fine in this bit of code. When I click the link it is supposed to pull the data from the database related to the $id. Code: [Select] <a href='javascript: window.document.Vids<?php echo $id; ?>.submit();'>Watch</a> <form name="Vids<?php echo $id; ?>" action="<?php echo $PHP_SELF; ?>" method="post"> <input value="<?php echo $id; ?>" type="hidden" name="Vids" /> </form> here is the code which is supposed to display the info. Code: [Select] if (isset($_POST['Vids'])) { $result = mysqli_query($link, "SELECT * FROM vidaud where id =".$_POST['Vids']); echo $id; the error i get is Quote Notice: Undefined variable: id in /services5/webpages/util/b/b/bbctech2.site.aplus.net/public/dbsite/a_newsite/sermons.php on line 32 I'm just not sure why the $id variable isn't being posted by my form and read by the code. Thanks. hidden input field type doesnt display the full value i get from table, say if it is a first name and last name i get only the first name. here is my input field echo "<input type=hidden name=proid value=$result_row[project_id]></include>"; echo "<input type=text value=$result_row[project_name] readonly></include>"; my sql query returns the full name but when i input into the text field it returns an incomplete project name like say if it is fans of soccer, i just get the value "fans" in my display..... I have a php index page that includes a form page with a delete button for that row. When I hit the delete button nothing happens. I am not sure if the variable is not passing or if the index.php page is not processing it correctly. Here is the index page that includes the form page: Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Welcome Page Test</title> <meta http-equiv="content-type" content="text/html; charset=utf-8"/> </head> <body> <?php if (get_magic_quotes_gpc()) { function stripslashes_deep($value) { $value = is_array($value) ? array_map('stripslashes_deep', $value) : stripslashes($value); return $value; } $_POST = array_map('stripslashes_deep', $_POST); $_GET = array_map('stripslashes_deep', $_GET); $_COOKIE = array_map('stripslashes_deep', $_COOKIE); $_REQUEST = array_map('stripslashes_deep', $_REQUEST); } if (isset($_GET['addjoke'])) { include 'form.html.php'; exit(); } $link = mysqli_connect('localhost', 'root', 'password'); if (!$link) { $output = 'Unable to connect to the database server.'; include 'output.html.php'; exit(); } if (!mysqli_set_charset($link, 'utf8')) { $output = 'Unable to set database connection encoding.'; include 'output.html.php'; exit(); } if (!mysqli_select_db($link, 'database')) { $output = 'Unable to locate the database.' . mysqli_error($link); include 'output.html.php'; exit(); } if (isset($_POST['joketext'])) { $joketext=mysqli_real_escape_string($link,$_POST['joketext']); $sql = "INSERT INTO jokes2 (joketext, jokedate) VALUES ('$joketext', CURDATE() )"; if (!mysqli_query($link,$sql)) { $error = 'Error adding submitted joke: ' . mysqli_error($link); include 'error.html.php'; exit(); } header('Location: .'); exit(); } if (isset ($_GET['deletejoke'])) { $id= mysqli_real_escape_string($link,$_POST['id']); $sql = "DELETE FROM jokes2 WHERE id='$id'"; if(!mysqli_query($link,$sql)) { $error= 'Error deleting actor: ' . mysqli_error($link); include 'error.html.php'; exit(); } header('Location: .'); exit(); } $result = mysqli_query($link, 'SELECT jokes2.id, joketext, name, email FROM jokes2 INNER JOIN author ON authorid = author.id'); if (!$result) { $error = 'Error retrieving data' . mysqli_error($link); include 'error.html.php'; exit(); } while ($row = mysqli_fetch_array($result)) { $jokes[] = array('id'=>$row['id'], 'joketext'=>$row['joketext'], 'name'=>$row['name'], 'email'=>$row['email']); } include 'jokes.html.php'; ?> </body> </html> The $_GET array should be getting the variable id passed when the Delete button is pressed on the form, but nothing is happening when I press the button.

Any ideas why this one is a problem? I'm new at PHP and have a problem. I have a MySql database with lists of students grouped into classrooms. A typical group is shown in the attached screenshot screenshot.docx. I want to be able to select one or more of the names by using the associated checkbox, and upgrade a student or students into a different group as defined in the radio button list also in the screenshot. I have the rudiments of the file attached, but I have absolutely no idea how I can post the array so that the records are updated. Each student has an individual record with a field name userGroup which holds a string nominated by their classroom teacher, such as "year7", "year 8" and so on while they are in one of the several classrooms, but when they leave school this is recorded in a field named noGroup with a value of 0 or 1. I can post further details as required, but it would be great if someone could help me. I have a menu that i want to be added to every page of my coding using a hidden variable, but i cannot get it to work. I using this with a few if conditions. the index page should navigate every page. can anyone help? I have attached the files to illustrate the coding i have done so far. [attachment deleted by admin] Here's my PHP form code: Code: [Select] <form method='POST' action="<?php basename($_SERVER['PHP_SELF']);?>" onSubmit="return stripInputBoxes(1)"> <?php echo "<div id = 'purchaseOrderRow1' style = 'display:none;border: 1px solid black;'>"; echo $integrityBuildingProductsPDF; echo '<input type = "hidden" id = "pdf1" value = "" name = "pdf1" />'; echo '<button name = "savePurchaseOrder" type = "submit">Save Purchase Order</button>'; echo "</div>"; ?> </form> Here's my Javascript: Code: [Select] function stripInputBoxes(pdfNumber) { if (!document.getElementsByTagName) return; for (i = 0; i < document.getElementById('tableBody').getElementsByTagName('tr').length - 3; i++) { document.getElementById(i).parentNode.innerHTML = document.getElementById(i).value; } document.getElementById("pdf" + pdfNumber).value = "ljkasdkljf"; return true; } Will this set the value of the hidden variable? I'm trying to echo the value of $_POST['pdf1'] but it comes out to nothing when the page reloads. How do I do this? What I'm trying to do here is display a purchase order on the screen and the user can edit the quantities in the purchase order. They click SAVE to save the new updated quantities and it auto generates a PDF that's saved on the server with those new quantities. The problem is I need to run the stripInputBoxes function to take the <input> tags out of the HTML code before creating the PDF because the PDF generator doesn't recognize the tags. Can someone please tell me what I am doing wrong here? For some reason, the variable doess not seem to be getting passed to the "action" php script this input is in my html form (action=post)... <input type="hidden" name="httpreferer" value="<?php echo $_SERVER['HTTP_REFERER'] ?>" /> this is in the action script... $httpreferer=$_POST['httpreferer']; echo $httpreferer; Code: [Select] <form action='test.php' method='post'> <input id="Username" type="hidden" name="date2" /> <input type="submit" name="action" value="Submit"></form> Hi I want to pass a Username javascript variable to test.php as hidden, anyone can help? When code this Code: [Select] <input id="Username" type="input" name="date2" />Data can pass to test.php When code this Code: [Select] <input id="Username" type="hidden" name="date2" />Data fail to pass over I have a mysql field that I want to store a php variable in and then retrieve it.
Example:
Color table has the field named colorBackground with the value of #FF0000
CSS table has the field named cssBackground with the value of .background { background-color: #444444; }
What I want to do is make Color/colorBackground a variable {{$backgroundcolor = rsColor['colorBackground']
Then I want to change the CSS/cssBackground value to .background { background-color:$backgroundcolor; }
Creating the $backgroundcolor works fine. I'm just not sure how to put the $backgroundcolor in my CSS/cssBackground field.
This is my first real jump into PHP, I created a small script a few years ago but have not touched it since (or any other programming for that matter), so I'm not sure how to start this. I need a script that I can run once a day through cron and take the date from one table/filed and insert it into a different table/field, converting the human readable date to a Unix date. Table Name: Ads Field: endtime_value (human readable date) to Table Name: Node Field: auto_expire (Converted to Unix time) Both use a field named "nid" as the key field, so the fields should match each nid field from one table to the next. Following a tutorial I have been able to insert into a field certain data, but I don't know how to do it so the nid's match and how to convert the human readable date to Unix time. Thanks in advance!. Hi: I'm going crazy trying to do the following: I'm making a job registration process where the user registers on one php page to the website, must acknowlege and email receipt using an activate php page, then is directed to upload their C.V. (resume) based on the email address they enter in the active page output. I then run an upload page to store the resume in teh MySQL db based on the users email address in the same record. If I isolate the process of the user registering to the db, it works perfectly. If I isolate the file upload process into the db, it works perfect. I simply cannot upload teh file to the existing record based on teh email form field matching the user_email field in the db. With the processes together, teh user is activated, but teh file is not uploaded. Maybe I've simply been at this too long today, but am compeled to get through it by end day. If anyone can help sugest a better way or help me fix this, I will soo greatly appreciate it. My code is as follows for the 2 pages. ---------activate.php------- <?php session_start(); include ('reg_dbc.php'); if (!isset($_GET['usr']) && !isset($_GET['code']) ) { $msg = "ERROR: The code does not match.."; exit(); } $rsCode = mysql_query("SELECT activation_code from subscribers where user_email='$_GET[usr]'") or die(mysql_error()); list($acode) = mysql_fetch_array($rsCode); if ($_GET['code'] == $acode) { mysql_query("update subscribers set user_activated=1 where user_email='$_GET[usr]'") or die(mysql_error()); echo "<h3><center>Thank You! This is step 2 of 3. </h3>Your email is confirmed. Please upload your C.V. now to complete step 3.</center>"; } else { echo "ERROR: Incorrect activation code... not valid"; } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <title>Job application activation</title> </head> <body> <center> <br/><br/><br/> <p align="center"> <form name="form1" method="post" action="upload.php" style="padding:5px;"> <p>Re-enter you Email : <input name="email" type="text" id="email"/></p></form> <form enctype="multipart/form-data" action="upload.php" method="POST"> <input type="hidden" name="MAX_FILE_SIZE" value="4000000"> Upload your C.V.: <input name="userfile" type="file" id="userfile"> <input name="upload" type="submit" id="upload" value="Upload your C.V."/></form> </p> </center> </body> </html> --------upload.php---------- <?php session_start(); if (!isset($_GET['usr']) && !isset($_GET['code']) ) { $msg = "ERROR: The code does not match.."; exit(); } if(isset($_POST['upload']) && $_FILES['userfile']['size'] > 0) { $fileName = $_FILES['userfile']['name']; $tmpName = $_FILES['userfile']['tmp_name']; $fileSize = $_FILES['userfile']['size']; $fileType = $_FILES['userfile']['type']; $email = $_POST['email']['user_email']; $fp = fopen($tmpName, 'r'); $content = fread($fp, filesize($tmpName)); $content = addslashes($content); fclose($fp); if(!get_magic_quotes_gpc()) { $fileName = addslashes($fileName); } include 'reg_dbc.php'; $query = "UPDATE subscribers WHERE $email = user_email (name, size, type, content ) ".

I know I am close because the UPDATE code works before I add the WHERE statement (it of course adds '666' to EVERY field, but for a noobie it's a start!). |
