PHP - Is This Not Possible.. Passing Disabled Inputs?
I have a field like this
<p>Price:</p> $<input type="text" name="price" size="5" disabled="disabled" value="<?= $price;?>"> Im using POST but if I try to echo $_POST['price'] nothing shows up... is it because its disabled? how can I do this if so? Similar TutorialsSo, I have a checkbox, like so: (uci is an ID number) <input type='checkbox' name='cars[]' value='".$row['uci']."' /> That is passed to the next page via the form. However I need to pass the id numbers again, through to a third and final page. Currently I'm trying to do it through hidden inputs, but all I get returned to me is the word, "Array". This is the second page, displaying the data it recieves from the checkbox on the first page and attempting to send it through to the third page via a hidden input. $ids = $_POST['cars']; ... Displays data here... ... <form action='step_3.php' method='POST'> <input type='hidden' name='cars' value='$ids' /> <input type='submit' name='submit' value='Final Step' /> </form> I also tried <input type='hidden' name='cars' value='".$_POST['cars']."' /> but that didn't work either. This is what I'm using to display the data on the final page, as a check to make sure it's working (this is where I'm just getting the word, "Array"): echo"Car Id's: ".$_POST['cars']."<br />"; So, I guess my question is how do I pass the multiple options checked on the first page through more than one page? It works fine displaying the data on the second page, however when I try to display it again on the third page via the hidden input, it doesn't work. Hello, I am doing a php registration form, file name is register.php Code: [Select] <?php include("config.php"); $submit = strip_tags($_POST['submit']); $username = strip_tags($_POST['user_box']); $password = md5(strip_tags($_POST['pass_box'])); $cpassword = md5(strip_tags($_POST['c_pass_box'])); $email = strip_tags($_POST['email_box']); $mobile = $_POST['mobile_box']; $ip = $_SERVER['REMOTE_ADDR']; $date = date('Y-m-d'); $time = date('h-i-s'); $i = 0; $checkusername = mysql_num_rows(mysql_query("SELECT * FROM members WHERE username='$username'")); $checkemail = mysql_num_rows(mysql_query("SELECT * FROM members WHERE email='$email'")); /* Validating username field */ if($username != NULL) { if (strlen($username) > 15 || strlen($username) < 6) { echo "<p>Username must be in range of 6 to 15 Characters.</p>"; } else { //check in DB if ($checkusername == 1) { echo "<p>Username already exist in database.</p>"; } else { $i++; } } } else { echo "<p>Username cannot be Blank</p>"; } /* ----------validating password field---------- */ if ($password != "d41d8cd98f00b204e9800998ecf8427e" || $cpassword != "d41d8cd98f00b204e9800998ecf8427e") { if ($password == $cpassword) { if (strlen($password) > 16 && strlen($password) < 4) { echo "<p>password must be in range of 4 to 16 Characters.</p>"; } else { $i++; } } else { echo "<p>Passwords do not match.</p>"; } } else { echo "<p>Password cannot be empty</p>"; } /* ----------Validating Passwords End---------- */ /* ----------Validating Email field Starts---------- */ if($email != NULL) { if($checkemail == 1) { echo "<p>Email already exist.</p>"; } else { $i++; } } else { echo "<p>Email field cannot be empty.</p>"; } /* ----------Validating Email fiend ends---------- */ /* ----------Validating Email field Starts---------- */ if($mobile != NULL) { if(strlen($mobile) >10) { echo "<p>Mobile cannot be more than 10 digits long</p>"; } else { $i++; } } else { echo "<p>Mobile field cannot be empty.</p>"; } /* ----------Validating Email fiend ends---------- */ if ($i == 4) { mysql_query("INSERT INTO members (username, password, email, mobile, ip, date, time) VALUES ('$username', '$cpassword', '$email', '$mobile', '$ip', '$date', '$time')"); echo "<p>Successful Registration Done !</p>"; } ?> <!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> </head> <body> <form id="form1" name="form1" method="post" action=""> <table width="576" height="229" border="0"> <tr> <td width="139">Username :</td> <td colspan="2"><label for="user_box"></label> <input type="text" name="user_box" id="user_box" size="30" height="30" /> (Between 6 to 15 Characters)</td> </tr> <tr> <td>Password :</td> <td colspan="2"><label for="pass_box"></label> <input type="password" name="pass_box" id="pass_box" size="30" height="30" /> (Between 4 to 16 Characters)</td> </tr> <tr> <td>Confirm Password :</td> <td colspan="2"><label for="c_pass_box"></label> <input type="password" name="c_pass_box" id="c_pass_box" size="30" height="30" /></td> </tr> <tr> <td>Email Address :</td> <td colspan="2"><label for="email_box"></label> <input type="text" name="email_box" id="email_box" size="30" height="30" /></td> </tr> <tr> <td>Mobile No. :</td> <td colspan="2"><label for="mobile_box"></label> <input type="text" name="mobile_box" id="mobile_box" size="30" height="30" /> (10 Characters)</td> </tr> <tr> <td> </td> <td width="171"><input type="submit" name="submit" id="submit" value="Submit" /></td> <td width="252"><input type="reset" name="button2" id="button2" value="Reset" /></td> </tr> </table> </form> </body> </html> When I load page, it shows following errors before Username cannot be Blank Password cannot be empty Email field cannot be empty. Mobile field cannot be empty. What I want is on loading page i.e. before giving any inputs, it should not show any errors. Need help How is it possible, in PHP, to display an error message next to a form input text field if a user is attempting to submit a form with empty fields? Moreover, how is it possible to remove the same error message when the user fills in the input field with the required data and/or refreshes the page? I have 2 files that I am working with: application.php and process.php.
application.php mainly has the HTML of the form. I am very new to learning PHP (I started learning it last week) and I have been searching for hours for a clear answer. I have already tried different methods for generating the error message including: using empty(), !isset, $_POST["name"] = "", etc, and have tried using session_start();, $row, echo, print, and other variables to try and display error message on the page, and I have tried using unset();, and = null, to try and remove the error message once the input field has been filled but all to no avail. Either the method I try only half works, or nothing works, and I cannot pinpoint which is the part that is not working. I only have 2 files to work with, and as an example of what I want to do is:
1. If the first name field is empty when the user clicks submit, an error message should appear next to the input. Is this possible with PHP? Hi there, Sorry if this is the wrong forum to post this in, If it is please feel free to move it to the correct one. I have a php page and I am trying to get a couple of lines to only be run if Javascript is disabled on the visitors browsers. Code: [Select] $returnpage = 'myphppage.php'; include('anotherphppage.php'); It is something probably simple but I can't see it... I have tried: Code: [Select] <noscript> <?php $returnpage = 'myphppage.php'; include('anotherphppage.php'); ?> </noscript> but that does not seem to work and I was hoping someone here would have an idea... Many thanks in advance Ross I have this function to get other website title tag. But since the fopen is disabled in my shared server, this function cannot work. How can i still do it? thanks in adv function getTitle($Url){ $file=@fopen($Url,"r"); if($file) { fclose($file); $str=file_get_contents($Url); if($str) { if(strlen($str)>0){ preg_match("/\<title\>(.*)\<\/title\>/",$str,$title); return $title[1]; } }else{ return true; } }else{ return false; } } is there anything i can use in replace of it to write permissions with system("chmod -R 777 \"$SET0/comments\" "); Hi, Is there away to enable system() for one of my websites? At the moment i'm receiving the following error message "system() has been disabled for security reasons". Thanks for any help. Hi all , here is a question about a disabled button . If I have a button: Code: [Select] <input id='submit' type='submit' disabled='disabled' value='submit'> Is it possible to change the "disabled=true" through php function ? such as Code: [Select] function change_button(){ echo "<script language=\"javascript\">"; echo "document.getElementById('submit').disabled=true;"; echo "</script>"; } I tried it , not working...is this function possible or have I make any mistake ? Thanks for every reply . The Error Message:
Warning: include(): http:// wrapper is disabled in the server configuration by allow_url_include=0 in C:\xampp\htdocs\ubergallery\multiple_image_upload\multiupload.php on line 27 Warning: include(http://localhost/ubergallery/multiple_image_upload/upload.php): failed to open stream: no suitable wrapper could be found in C:\xampp\htdocs\ubergallery\multiple_image_upload\multiupload.php on line 27 Warning: include(): Failed opening 'http://localhost/ubergallery/multiple_image_upload/upload.php' for inclusion (include_path='.;C:\xampp\php\PEAR') in C:\xampp\htdocs\ubergallery\multiple_image_upload\multiupload.php on line 27I am getting this error message. Including a stylesheet or a jquery file with the absolute path does work out, with this I was looking to include a PHP script with the absolute path. Here is the code:

Any suggestions what to do here?
This topic has been moved to JavaScript Help. http://www.phpfreaks.com/forums/index.php?topic=308032.0 Hi, I have an HTML form with a "submit" button that sends form data to a PHP script. Firstly, the form doesn't seem to send the data to the PHP script, unless I include a line in the PHP script as follows: $var1 = $_REQUEST['var1']; Is this always the case or is there a way to automatically have the form send through data? The reason I ask is because the form includes elements that can be disabled, in which case (if element 'var1' is disabled) the above PHP line returns an error "Notice: Undefined index: var1" i.e. I want to only send through data from enabled elements and not from disabled elements. Alternatively, is there a line I can include in the PHP script something along these lines: if (defined($var1)==FALSE) {$var=" ";} so that when the PHP script tries to retrieve var1, which is undefined because the corresponding form element has been disabled, it sets it to a particular value. my HTML form is along these lines: Code: [Select] <form action=something.php method=POST> <select id="var1" name="var1"> <option> </option> <option selected="selected"> option1</option> <option> option2</option> <option> option3</option> </select> <input type="submit" value="next"> </form> Thanks! I need a calendar that is setup if you select a date that is within a 7 days of the current date then a radio button the the page is not available to be selected. how do i enable exec() in php.ini? where is php.ini? cant find it in the directories in my site. Does anyone have any idea why my inputs shrink (to default height and weight) after i press submit button? I use css width and height for inputs. All other settings (border, background color etc.) remain like they should. For form submit i use PHP self function where i check if submit button has been pressed and then perform the form action. Thank you Hello All, I'm working on this project, and everything was great but the last part is screwed. The procedure is supposed to be, you choose a hotel ---> book a room ---> confirm the booking and enter your details --> get redirected to paypal Everything is fine except for the confirmation part, where you're supposed to confirm the room you booked, number of nights and so on, all the info is right, except for the booked room, where it should show you the price for the room multiplied by the number of night... instead it gives "Total Price = 0" So anyone can give me an example on how can I make it show the result of multiplying 2 inputs by a user? Variables are $nrooms $newdate Here is the code I wrote Code: [Select] <?php $dbo = new DB(); $hotelObj = new hotelManager(); $hotelID = $_POST['hotelid']; $datein = $_POST['datein']; $dateout = $_POST['dateout']; $roomid = $_POST['roomid']; $roonsNo = $_POST['roomsNo']; $pr = $_POST['pr']; $_SESSION['hotelID'] = isset($_POST['hotelid']) ? $_POST['hotelid'] : $_SESSION['hotelID']; $_SESSION['datein'] = isset($_POST['datein']) ? $_POST['datein'] : $_SESSION['datein']; $_SESSION['dateout'] = isset($_POST['dateout']) ? $_POST['dateout'] : $_SESSION['dateout']; $_SESSION['roomid'] = isset($_POST['roomid']) ? $_POST['roomid'] : $_SESSION['roomid']; $_SESSION['nrooms'] = $_POST['nrooms']; $roomsarray = explode(",",$_POST['roomid']); $_SESSION['roomsarray'] = isset($_POST['roomid']) ? explode(",",$_POST['roomid']) : $_SESSION['roomsarray']; $roonsNo = $_POST['nrooms']; $_SESSION['nrooms'] = isset($_POST['roomnum']) ? explode(",",$_POST['roomnum']) : $_SESSION['nrooms']; /********************** hotels ************************/ /******************************************************/ echo "<table width=95% border=0 align=\"center\" cellpadding=\"0\" cellspacing=\"0\"> <tr><td valign=\"top\">"; echo "<table>"; echo "<tr>"; echo "<td valign=top>"; $imageqry=mysql_query("SELECT * FROM `hotelphotos` where hotel_id='".$_SESSION['hotelID']."' LIMIT 1"); $image=mysql_fetch_array($imageqry); $imagename=$image['attachmentName']; echo "<img src=\"foxmaincms/webroot/files/small/$imagename\"/>"; echo "</td>"; echo "<td>"; $result=$hotelObj->getHotelbyID($_SESSION['hotelID']); $row = mysql_fetch_array($result); echo "<table>"; echo "<tr><td valign=top><strong class=subtitle3>".$row['name']."</strong></td></tr>"; echo "<tr><td class=text valign=top>".$row['location']."</td></tr>"; echo "<tr><td class=text valign=top>check-in Date: ".$_SESSION['datein']."</td></tr>"; echo "<tr><td class=text valign=top>check-out Date: ".$_SESSION['dateout']."</td></tr>"; echo "<tr><td class=text valign=top>"; $newdate = $_SESSION['dateout'] - $_SESSION['datein']; $totalprice = $nrooms * $newdate; echo "</td></tr>"; echo "<tr><td class=text valign=top>Total Price: ".$totalprice."</td></tr>"; echo "</table>"; ?> Hi! I wanna know what is the best way to secure my inputs? Now I'm using something like this function:
public function z($var) {
$result1 = htmlspecialchars($var);
$result = mysqli_real_escape_string($this->conn, $result1);
return $result;
}
but I don't know how secure it is from all inputs... It couldn't be that with that my site is completely secure... So I wanna know what else I should use... I found something about PHP sanitize filters and similar... Same for mail, should I use that for e-mail, what should I use for e-mails as I think this 2 codes will brake character @ necessary for emails. Any suggestion is welcome Thanks I'm working on an online php program that can have a few hundred form inputs. Mainly just numbers from 1 to 50,000 depending on the field. I wanted to use cookies so the user can keep the data entered on their browser but i found out the hard way that the browsers have a limitation that I've exceeded. Does anyone have any ideas? Hey guys I have a lot of inputs from my form. Is there a way I can do like a for each or something instead of of having to write $myusername = stripslashes($_POST['name'); $mypassword = stripslashes($_POST['pass']); $myusername = mysql_real_escape_string($myusername); $mypassword = mysql_real_escape_string($mypassword); .... for all 16 fields? thanks II have been told that I should sanitize my inputs, what does that mean? Isn't that what trim does? What is the best way to force a user to input numeric value into a form, with the following condition: Either the number is an integer (positive or negative or zero), or non integer but limited to the one digit behind the dot (e.g. 1.2 is valid, but 1.21 is not)? I know I can test it in the server side, but I prefer it to be on the form side. Can it be in the HTML level? |
