PHP - Passing Checkbox Values Through Hidden Inputs?
So, 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. Similar Tutorials

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 Hello there, I've been searching for the answer to this for a while but haven't got anywhere. I'm fairly new at the whole PHP scripting so I maynot be phrasing it correctly Basically I just want a couple of things to happen: 1) A user registers and is shown a page confirming successful registration. This page confirms there details, tells them an email is on the way and they may now login. The problem lies here, I have made it so it inputs the username into the url. For example we end up with something like www.xxxxx.com/login.php?user=Jacketh. I would like it so that username value is input into the Username: input type on the login page. I'm guessing there must be some coding as that link doesn't actually put anything into it, the input does have id and name both as user. 2) Pretty much the same for the email confirmation, the link does the same and creates a query string that inputs the info into the specific fields. Is there a way to then click the submit button automatically or something? Hence if I input there username and password through the string and enforce automatic login? This would be nice if possible! Thanks, Jacketh 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] 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; 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.

Two things I've figured out today: 1) a form input doesn't need a value - doesn't even need the attribute - if you're only checking whether the POST var isset and the actual value isn't important 2) Although it appears not to matter in the example I'm working on now, if the script doesn't check what the value is, and potentially sanitise it, the user could submit the form with any value, true, false, malicious, idk... So my question is: is this one of the ways malicious bad things can happen and do I *have to* specify a value, not because the script won't work without it, it does, but because in the real world it opens a security door if I don't check for malicious script by saying "if value not as expected, script has to die". Having formulated the question properly and thought about it I can't imagine simply making a form, without obvious connections to anything important, could be a problem in the way I'm asking about but I asked it now so Edited by appobs, 03 July 2014 - 12:08 PM. I am passing value to AJAX function, but always shows undefined.. It works fine two days ago, but not today..

I have tried to use sessions but it didn't work out for me. Any suggestions! If I store a value in a hidden form control, and then use that as a means to pass the value to another PHP script, could that cause any security issues?
I have a form that has a list of checboxes, each checkbox has multiple values. IE. Checkbox1 has Date 1 and Cost1. Checkbox2 has Date2 and cost2 and so on. This is what I have in form. echo "<input type=checkbox name=service_id[] value=".$id."><label>".$description."</label> Date:<input type=date name=date[] value=".date('Y-m-d').">Date:<input type=number name=cost[] value=".$cost."><br>"; When i run the for loop to insert the values into a table i have this.
foreach($_POST['service_id'] as $key => $value){
The problem is that when I select certain boxes (ie, checkbox #2), it inserts Date1 and Cost1 but does use the correct service id (ie checkbox) I have a form and on each input I set the value as the post variable of it's self. I do this so that if the user submit the form and it has errors they haven't lost the data they have inputted. For example <input name="input1" type="text" value="<?php echo($_POST['input1']); ?>" /> This works fine for text field and textarea's but how do I retain the value of radio boxes and checkboxes? Basically i made a form with checkbox using post.. here's the form Code: [Select] <?php echo '<form name="formupload" method="post" action="val3.php">'; echo '<input type="image" src="images/reject.png" name="test" width="170" height="35" border="0" value="reject">'; echo "<table border=\"5\" >"; echo "<tr><th>List of Instructor</th>"; if(mysql_num_rows($result)) { while($row = mysql_fetch_assoc($result)) { echo "<tr><td>"; echo "<input type='checkbox' name='list[]' value='".$row['fullname']."'>" .$row['fullname']."<br/></td>"; echo "</tr>"; } } else { echo "<tr><td>No one to Approve</td></tr>"; } echo '</form>'; ?> Then my val3.php will output the values of the checked checkbox. here's the code. Code: [Select] <?php foreach ($_REQUEST['list'] as $checkbox) { echo $checkbox; echo "<br/>"; } ?> Now i don't know how to insert those values to my database.. help pls. Is is possible to give multiple values in a single checkbox? i need to have a checkbox that holds multiple values. Help Anyone.. Trying to get a form to display checked and unchecked values based on what is in the database. Hard coded form works fine. I implode the array and it goes into the database as a comma delimited string. But I need to let users edit the checkbox values, so I need to create the form by exploding the string, iterating through the array, and outputting the checkbox form elements. Here's what I have... Code: [Select] <p>Specialization: <p> <?php //echo $session->userinfo['specialization']; THIS DISPLAYS THE STRING CORRECTLY $aSpecialization = array('Automotive', 'Aerospace', 'Biotech/Life Sciences', 'Chemicals', 'Damages Analysis', 'Electronics', 'Litigation', 'Manufacturing ', 'Materials', 'Medical Devices', 'Mobile Applications', 'Patent Prosecution', 'Physics', 'Renewable Energy', 'Semiconductors', 'Software', 'Telecommunications', 'Utilities'); //converting comma separated into array using explode function $dbspecialization= explode(',',$session->userinfo['specialization']); // echo $dbspecialization; THIS IS CONFIRMED AS AN array foreach ($aSpecialization as $specialization) { if(in_array($specialization,$dbspecialization)) { echo '<input name="specialization[]" type="checkbox" value="$specialization" CHECKED> $aSpecialization[] <br />'; } else { echo '<input name="specialization[]" type="checkbox" value="$specialization"> $aSpecialization[] <br />'; } } ?> But the output I get is... Code: [Select] <input name="specialization[]" type="checkbox" value="$specialization" CHECKED> $aSpecialization[] <br /> <input name="specialization[]" type="checkbox" value="$specialization"> $aSpecialization[] <br /> <input name="specialization[]" type="checkbox" value="$specialization"> $aSpecialization[] <br /> etc... What am I missing? hey guys i am stuck at one part. i am coding a site where on the index page there are 5 categories. Now on click of these it takes me to a page where i can search within a particular category. i can do it by statically giving <href="localhost/xampp/abc.php">and a fixed page path. but i want the name of the category passed when i click and the search page to open when i open search. thanks Hi guys
I would like to get whole content of html file after I submitted a password. The problem is that the my code doesn't access the value for the file. I tried to create a session but i doesn't work. What other option do I have to get the content of the html file?

What I have is a page with a list of cars, each with a checkbox next to them. Code: [Select] <?php $sth = null; $count = 0; $sth = $dbh->prepare("SELECT * FROM garage WHERE warehouse_id = ? ORDER BY car_name ASC"); $sth->execute(array($_POST['ware_id'])); echo "<table>"; echo "<tr>"; echo '<td>Choose Vehicles:</td>'; echo "</tr>"; echo "<tr>"; echo "<td>"; echo "<form action='warehouse_ship_3.php' method='POST'>"; while($row = $sth->fetch()){ echo "<input type='checkbox' name='cars' value='".$row['uci']."' /> ID: ".$row['uci'].", ".$row['car_year']." ".$row['car_name']."<br />"; } echo "<input type='hidden' name='ware_id' value='".$_POST['ware_id']."' />"; echo "<hr />"; echo '<div class="center"><input class="myButton" type="submit" name="submit" value="Next" /></div></form>'; echo "</td>"; echo "</tr>"; echo "</table>"; ?> That works fine. What I'm trying to do with this second page, is select all the car's info from a table called "garage" which stores data for all the cars (car name, year, etc) and display it. UCI stands for Unique car id, every car has a different id. It works when the user only selects one car on the previous page, but if they select two or more cars, only the car with the highest UCI number shows up. How would I work it to display info on every car that they selected? Code: [Select] <?php if(empty($_POST['cars'])) { echo("You didn't select any cars."); } else { $sth = $dbh->prepare("SELECT * FROM `garage` WHERE `uci` = ?"); $sth->execute(array($_POST['cars'])); while($cars = $sth->fetch()){ echo" ".$cars['uci'].", ".$cars['car_year']." ".$cars['car_name']." "; } } ?> |
