PHP - Code "back" Button To Retain Values From $_post
Hi,
I have set up 2 php pages page 1 - add_entry2.php In this page I have a invoice table created where I can dynamically add/delete rows. This has a View Bill button which takes me to page 2- add_entry3.php In this page it shows up the rows added in page 1 in read only format, so if the user wants to modify the data that he/she entered then he must Click on <back> that i have provided in the page 2 which will direct him to page 1 Now the problem starts here on click of Back the dynamically added rows dissappear..which is frustrating..I know its something to do with my code..but can anyone help me fix it. One more thing is that i dont want to store the data into DB till the finalise button is clicked on page 2 so that means till page 2 is submitted nothing goes to DB from Page 1. I am able to retain values if I use the code Code: [Select] <form action="add_entry2.php" name="eval_edit" method="post" format="html"> i,e if I submit back to the same page and retrieve values form $_POST but If I use the code Code: [Select] <input type="button" value="Back" onClick="history.go(-1);return true;">to get back to add_entry2.ph it looses all the values. Is there any other way to code the BACK link retaining my $_POST values(Do you think $_SESSION would work in this case?) Similar Tutorials"BACK" or REFRESH: Preventing database interaction / code execution how to prevent database interaction / code execution when user presses back or refresh button? can i detect? can i disable back/refresh? Hi, bit stuck on how to find and replace "<" and ">" with "<" and ">". I basically have a database record that outputs to screen and I need the code in the <code> tags to be rendered to the screen. I therefore need it to go through the whole array variable from the db and change the symbols just inside the code tags. Please be aware that the code tags might happen more than once here's an example below Code: [Select] <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1> </code> <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1> </code> the desired output would be: <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1 </code> <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1 </code> help on this would be great Cheers Rob hello, I was wondering what is the point of writing for a dropdown: <?php if ($_POST[inputfieldID] == "value") { echo "selected"; } ?> or for a checkbox/ radio button: <?php if ($_POST['cb/radioID'] == "value") { echo "checked"; } ?> I guess it's for after submit, if there is any error, the values filled will still be echoed in the inputfield, or am i wrong? But then if that is true, i have a php search box where i use AJAX object to to send all the input they filled in after submit. But after pushing submit the inputted values remain. I guess when using AJAX to send the information i don't need <?php if ($_POST[inputfieldID] == "value") { echo "selected"; } ?> in my html forms? Little confused Can maybe somebody bring clearness Can someone please help me with an array problem i can not figure out. I need the array to be numbered from 1 to how ever many fields that are needed in the form and have a mysql field name and the title of the field also in the array. 1, "mysql_field_name", "Title of form field" 2, "", "" and so on then the form will be shown based on the array. I have the following draft code which I am working with. any suggestions on how i may do this array ? Code: [Select] <?php $options = array( '1'=> array('fieldtext'=>'option1', 'mysqlfield'=>'option1'), '2'=> array('fieldtext'=>'option2', 'mysqlfield'=>'option2'), '3'=> array('fieldtext'=>'option3', 'mysqlfield'=>'option3'), '4'=> array('fieldtext'=>'option4', 'mysqlfield'=>'option4'), ); // $options = array(1 => "option1", "option2", "option3", "option4"); // the line above works but i want to include the name of the mysql field as well. $userid = 1; ?> <div style="align: center; margin: 12px; font-family:Tahoma;"> <br><br><?php if ($_POST['Update'] != "Update") { // check if form submitted yet, if not get data from mysql. $res = db_query("SELECT * FROM `users` WHERE `userid` = '" . $userid . "'"); foreach($options as $key => $value) { $_POST[$key] = mysql_result($res, 0, $value); } $ok_to_update = "no"; } elseif ($_POST['Update'] == "Update") { // check if form submitted yet, if so get POST data. // error checking // foreach($options as $key => $value) { // $_POST[$i] = ""; // } $ok_to_update = "yes"; } if ($_POST['Update'] == "Update" && $ok_to_update == "yes") { // $res = db_query("INSERT INTO `users` () VALUES ()"); // add user details to database. ?><p><br><br><br>Thank you for updating</p><?php } else { ?><form name="form1" method="post" action=""> <?php foreach($options as $key => $value) { ?><p><?php echo($value); ?>: <input type="text" name="<?php echo($key); ?>" value="<?php echo($_POST[$key]);?>"></p> <?php } ?> <input name="Update" type="submit" value="Update"> </form> <?php } ?> </div> preg_replace() asks that "Delimiter must not be alphanumeric or backslash" in the pattern. So I changed $new_text = preg_replace($_POST['withthis'] ,$_POST['withthis'],$_POST['text']); to this $replacethis = $_POST['replacethis']; $new_text = preg_replace("/$replacethis/",$_POST['withthis'],$_POST['text']); It works fine, but out of curiosity, is there any way to have the POST variable as a parameter directly, and why does it not work? Just to try it, I attempted: "/$_POST['withthis']/" and $_POST["/'withthis'/"] and both do not work. str_replace is a better option I think, but I am just trying to get a better understanding of this delimiter rule. Thanks for your time! Code: [Select] <?php if (isset($_POST['submit'])) { // Grab the selected value $optionValue = $_POST['subscriptionLevel']; // Grab the id of the selected value ** HOW DO I DO THIS? ** $optionID = ?????????????????????????; } ?> <html> <body> <form name="form" method="post" action=""> <table> <tr> <td> <label for="subscriptionLevel"></label> <select name="subscriptionLevel" id="subscriptionLevel"> <?php do { ?> <option id="<?php echo $dbRowResult['sub_level']; ?>" value="<?php echo $dbRowResult['sub_price']; ?>"><?php echo $dbRowResult['sub_desc']; ?></option> <?php } while ($dbRowResult = $db->dbGetRow($dbQueryResult)); ?> </select> </td> <td> <label> <input type="submit" name="submit" id="submit" value="submit"> </label> </td> </tr> </table> </form> </body> </html> How do I grab the id of the selected value? Thank you. I want to post some form identifyer when I hit submit, so that I can use this in an SQL query. Previously I used the below code and would retrieve either page1.php or page2.php etc from $_POST['subject']); Code: [Select] <td> <select name="subject" id="subject" onchange="gotourl(this.value)"> <option value="" >Please Select</option> <option value="page1.php" >page1</option> <option value="page2.php">page2</option> <option value="page3.php">page3</option> </select> </td> will this work? Code: [Select] <form id="form1" name="form1" value="tableName" method="post" action=""> $_POST['form1']) returns tableName...... Thanks Hi All, I'm having trouble with an email I'm trying to send out. While testing my code, the email that my script sends has the "Reply-To" email address in the headers but when I click "reply", the recipient's email, $to in the code below, is inserted instead of the "Reply-To" email. Am I missing anything? Thanks for the help in advance! $to = "abc@email.com"; $headers = "From: " .$admin_name. "<" .$admin_email. ">\r\n"; $headers .= "Reply-To: " .$host_name. "<" .$host_email. ">\r\n"; $headers .= 'MIME-Version: 1.0' . "\r\n"; $headers .= 'Content-type: text/html; charset=iso-8859-1' . "<br>"; $subject = "Subject"; $body = "Body"; mail($to, $subject, $body, $headers); Cannot modify header information - headers already sent by (output started at ) on line 179 I labeled 179 its at the bottom. I understand this means its already generating the html but not how or where. A solution would of course be nice but if some one could tell me even how to figure it out it would be great.

Hey guys, I'm new here so hello... but I'll get right to the point: I have a table named POSTS, where I store user posts. In this table, I have a row named "Popularity". Now I would like the value of "Popularity" to be a function of the number of Likes, Dislikes, Views and Date posted, all of which are stored in respective tables (linked by Primary and Secondary keys). I was wondering if it actually is possible to have the value of "Popularity" adjust automatically when a change in "Likes", "Dislikes" or "Views" occurs. And if not, what alternatives I have. The ultimate reason I need to have this value stored in a table and up to date is that I wish to sort posts by "Popularity". Many thanks !!!
