PHP - Is This $_post Considered Empty
I am trying to code a error callback using php and ajax.
What I cannot get past is, I am assinging a variable to a $_POST in PHP to check for an empty value. If empty, then trigger error message. However, jquery is passing the post to php as carton%5B0%5D:carton%5B1%5D:. Would php see this as an empty post? What are these numbers etc after carton? carton is actually an array. If I do elseif(!empty($carton)) then the message is triggered. This is strange bearing in mind that the input values are empty at submit stage. thanks This is the code that jquery uses to create an input from a slider change event. Code: [Select] for(var i = 0;i < $(this).val();i++) { $("#carton").append('<div data-role="fieldcontain"><label for="carton" class="ui-input-text">Enter box ' + (i + 1) + ' number:</label><input type="text" name="carton['+i+']" id="carton['+i+']" class="carton ui-input-text ui-body-null ui-corner-all ui-shadow-inset ui-body-c" /></div>') } sample php code Code: [Select] $carton = $_POST['carton']; elseif(empty($carton)) { //set the response $response_array['status'] = 'error'; $response_array['message'] = 'You must enter a carton for retrieveal'; //if no errors } Similar TutorialsHi, i'm new here and hope i've finally found a forum where i can find the perfect solution for my questions.
Well since a year now i started to work with PHP and still now and then there are some things where i seize on. My question is on of those situations.
I have the following code:
if (isset($_POST)){
foreach ($_POST as $key => $value){
if (!empty($value)){
$update_rma_detail_stmt = $dbh->prepare("UPDATE rma_detail SET $key = ? WHERE rd_rma_nr = ?");
$update_rma_detail_stmt->bindParam(1, $value);
$update_rma_detail_stmt->bindParam(2, $getadmrmaid);
$update_rma_detail_stmt->execute();
}
}
}
All i want is when there is an empty (not filled in) input field because it is not mandatory the foreach still continuous to the end.
When i use
if (!empty($value)){
It still outputs these error:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000]: General error: 1366 Incorrect integer value: ' '
However, when i dont use i got an other error:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[22007]: Invalid datetime format: 1292 Incorrect date value: ''
It is however so that the datetime is the very first empty field it come across when looping. I think my if (!empty($value)){ is doing the right thing but still gives error's on integers. Can it be? I allready tried to use trim() or array_filter() but because i previously never used it i dont know if i am doing it the right way so any help is welkom!
Thanks!
Edited by Raz3rt, 20 May 2014 - 02:56 AM. Hello all! I have a page that dynamically generates checkboxes in a for() loop if $i<$product_qty, while it is generating the checkboxes the name for them is set like this $product_id_$i. In part of the next page that processes the checkboxes, I have a part that regenerates the names for those checkboxes using a for() loop again and the product_qty and then checks to see whether the checkbox is empty or not. Everything looks right in the for() loop, yet the if() that checks whether it isset or not just ignores the ones that are set. If I make a static if with the actual name of the checkbox the if() comes back as true. I've hit a brickwall, can anyone see any errors in my code? Code is below. // Get Old Order $get_order = @mysql_query("SELECT * FROM orders WHERE order_id = {$_POST['order_id']}"); $order = @mysql_fetch_assoc($get_order); // Get Old Order Items $products = $order['products']; //breaking products text down for display $prod = array(); $_products = explode('|', $products); foreach ($_products AS $p) $prod[] = explode(',', $p); if(empty($prod)) { header("Location: tracking.php"); die(); } /* // Create New Order @mysql_query("INSERT INTO orders SET customer_id = {$order['customer_id']}, order_status = {$order['order_status']}, order_date = '{$order['order_date']}', order_date_paid = '{$order['order_date_paid']}', order_shipping = '{$order['order_shipping']}', order_shipping_fee = '{$order['order_shipping_fee']}', order_insurance = '{$order['order_insurance']}', order_insurance_fee = '{$order['order_insurance_fee']}', order_insurance_total = '{$order['order_insurance_total']}', order_grand_total = '{$order['order_grand_total']}', order_date = '{$order['order_date']}', order_filled = '{$order['order_filled']}', order_ship_date = '{$order['ship_date']}'"); $get_new_order = @mysql_query("SELECT MAX(order_id) AS order_id FROM orders"); $new_order_id = @mysql_result($get_new_order, 'order_id', 0); */ // Add Items to New Order & Remove Items from Old Order $new_items = array(); foreach($prod as $p2) { for($i = 0; $i < $p2[0]; $i++) { if(!empty($_POST[$p2[3].'_'.$i])) { $new_items[$p2[3]]++; } } } if(isset($_POST['50_4'])) { echo "hi"; } TIA! Jonathan I know what OOP PHP is but I can't grasp it exactly in relation to a website. For instance in order to be considered OOP PHP would all your pages need to be "webpage" objects with variables like "header", "footer" and "content" and then passing all the pages html to this class. Would it still be considered OOP PHP if the html of the webpage was written out for each page (assume we are coding a car dealership) and only objects like "car" and "salesman" were created. <?

Hi this coding works on another website although I have reduced it down here for clarity. I have had my website moved to another server and I can't connect now.If there is a better way? I was given this coding from someone on this website about 4 years ago. I didn't want to use a strait connect because when there was difficulty connecting to the database I received an error giving me and any hacker all the details of the database server. This was to be a more controlled access. Edited by ignace, 09 June 2014 - 01:34 PM. Hi,
I've noticed that many members routinely recommend intval() for “sanitizing” user input. I think this is a very bad idea for a couple of reasons:
PHP integers are stored in 32 bits or 64 bits depending on the platform. This is not enough to cover all MySQL integer types. For example, a 32-bit PHP integer can neither hold an INT UNSIGNED nor a BIGINT. And even a 64-bit PHP integer cannot hold a BIGINT UNSIGNED. That's obviously a problem and can lead to very nasty truncation bugs.
Silently changing the user input is very confusing and potentially harmful. Let's say the user tries to delete a record, but the provided ID is not numeric. This is clearly an error. Either the user has entered a wrong value, or there's an application bug. In any case, the request cannot be processed safely and should be rejected. What the intval() does instead is turn the invalid input into a “random” ID and pass it on to the database system to delete the record. Bad idea!
Many people already struggle to understand the difference between mysql_real_escape_string(), addslashes(), htmlentities(), filter_var() etc. Now we have yet another function in the ever-growing pool of “sanitize” functions. This doesn't really help.
So I think intval() should never be used for data “sanitization”. Just use the appropriate escape function like mysql_real_escape_string().
Man, I'm having a rough week with questions--if you're following at home. Basically matching a Coach's first and last name to another table, which if matched will yield information about that coach's team. Code: [Select] // or get user by username $current_user = wp_get_current_user(); $current_first = $current_user->user_firstname; $current_last = $current_user->user_lastname; $current_id = $current_user->ID; echo '<div class="contact_form">'; echo $current_first . ' ' . $current_last .' :: '; $query = "SELECT * FROM schools WHERE coachFirst='".$current_first."' AND coachLast='".$current_last."'"; $result = mysql_query ($query); if(!$result) { echo 'There is not a match for your name.'; } else { while($school= mysql_fetch_array($result)) { echo $school['school'] . ' ' . $school['id']; include(ABSPATH ."wp-content/plugins/my-team/form.php"); } echo '</div>'; echo '<div class="roster">'; include(ABSPATH ."wp-content/plugins/my-team/roster.php"); echo '</div>'; } What I am looking for is that if any field in a database is empty, the form comes back and puts in the word "empty" into the web page, but not the database. I got this right now, it shows the first part fine, but the second part it doesn't show the "Empty" comment... I don't understand why... as far as I can tell the code is fine... Code: [Select] <?php //Nonconformity, Disposition, Comments and Comments & Additional Details echo '<div id="box3">'; if (!empty($row['Nonconformity']) || !empty($row['Disposition']) || !empty($row['Comments']) || !empty($row['CommentsAdditional_Details'])) { echo '<div id="non"><span class="b">Nonconformity: </span><br />' . $row['Nonconformity'] .

I have a hidden field that holds it in each step... what am I overlooking? I have a button that uses $_POST to send information to another page. The data is in a hidden input so it's not possible for users to change information. I have nothing to check if the data is correct on the other page. Is it still possible for people to change the $_POST data though? Or somehow send false $_POST data to the other page? I want to link this two file but not working,
first file to make drop down option form Running into some problems with my code. I am having the user search the Database with either a UAID or the user's full name. It works fine when you input both the UAID and name; however, I want it to work if only one is give (i.e. just the name or just the UAID). I decided to use the isset($_POST) function of php but I am not getting it to work correctly. PHP believe it is set even though it is empty.
