PHP - Best Way To Check If Form Field Is Set?

Ok so i have registration page on my webs but i didn't work on empty fields so how could i check all fields?
Code: [Select]
//if no name
if(!$name){
$error = "Username missing.";
}
//if no pass
if($pass == false){
$error = "$error,Password missing";
}
//if no pass conf
if($pass_conf == false) {
$error = "$error,Pass conf missing.";
}
//if no email
if($email == false){
$error = "$error,Email missing.";
}
//pass conf
if($pass != $pass_conf){
$error = "$error,Passwords do not match.";
    }
    echo "<script>alert('$error');</script>;";
//header("Location: register.php");
 My script gives same results every time (even if i fill any of fields)...also if i un-comment header command it wont show alert..it just reloads the page

So can anyone help me with this?
Thanks..

I have a code which I made just up
  Code: [Select]
<?php if ($product->title == '01'); print "Earring"; ?>
<?php if ($product->title == '02'); print "Necklace"; ?>
<?php if ($product->title == '03'); print "Necklace"; ?>
<?php if ($product->title == '04'); print "Ring"; ?>I just want to check the product titles first 2 characters and print according to that.
Example: If $product->title is "01DSE32" print Earring. This checking must be strgn  or something like that which I don't remember. I would appreciate some feedback.

I have this script running:


<?php
$query = mysql_query("SELECT * FROM jobs WHERE event = 'Yes' ORDER BY title");
while ($row = mysql_fetch_array($query)) {
?>


How do I check if a field is empty and NOT display it...?

For instance it has a 'applied' field, if that is empty I dont want it to display, however I still  need the event = 'Yes' part.

Hello there,

My current song request form process looks like:

<?php
                if(isset($_POST['submit'])) {
                $to = 'address@website.com' ;  
$name = trim($_POST['name']);
                $message = trim($_POST['message']);
                $artist = trim($_POST['artist']);
                $song = trim($_POST['song']);
$subject="Name:$name - Message:$message - Artist:$artist - Song:$song";
                $headers  = 'MIME-Version: 1.0' . "\r\n";
                $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
                $message = "<table>
                <tr><td>Name</td><td>".$_POST['name']."</td></tr>
                <tr><td>Message</td><td>".$_POST['message']."</td></tr>
                <tr><td>Artist</td><td>".$_POST['artist']."</td></tr>
                <tr><td>Song</td><td>".$_POST['song']."</td></tr>
                </tr></table>" ;
                mail($to, $subject, $message, $headers);
                header('Location: song-requests-success.php');
               }
?>

I'm currently using Javascript for blank validation, however, people seem to be getting through it somehow.

I'm looking to implement PHP checkers that will output back to the request form with something like: Name field blank.

Would this method work?

$name = trim($_POST['name']);
$artist = trim($_POST['artist']);
$song = trim($_POST['song']);
if(empty($name)){
$name1 .= "<br>Name is empty.";
}
if(empty($artist)){
$artist1 .= "<br>Artist is empty.";
}
if(empty($song)){
$song1 .= "<br>Song is empty.";
}

On form:

<?php if(!empty($name)){ echo "".($name1).""; } ?>
<?php if(!empty($artist)){ echo "".($artist1).""; } ?>
<?php if(!empty($song)){ echo "".($song1).""; } ?>

Would recalling the trim's be nessessary as they have already been specified for the email title. Would this need to be implemented into 'isset'.

Many thanks.

Pehaps this is kidstuff but i'm a kid at heart.

I have only 1 form field on a form
User enters a special code in the form.
Once submitted the form is queried against a mysql database to see if the code exists.
If code does not exist it must be reentered.
If code exists then redirected.

basically its like "get to the next page if you have the code"

thanks

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 there once again, sry for previous wrong section, i guess this time i'm on the right place ;p

Well i need following:

I have few forms (input fields) with requested informations, also i have other .php file which i'm calling to send a form. Now i need to know how can i do a check for those fields if they are empty or not. If they are, i need to STOP submiting the form (calling the other .php).

Codes:

Form:
Code: [Select]
<form name="f1" form method="post" action="posalji.php"/>Field:
Code: [Select]
<input type="text" name="hp1" size="20"/>Submit:
Code: [Select]
<input name="f1" type="image" src="registruj.png" onclick="if(f1.hp1.value.length==0) alert('Error: field can't be empty'); else f1.submit(); if(f1.hp2.value.length==0) alert('Error: field can't be empty'); else f1.submit();"/>There are more than one field, that's why you can see more errors in submit. Well all i need is "die" or "stop" calling the "posalji.php" from action above.

Sry 4 poor english.

I am building a system where people are able to choose a food menu, they can modify each dish if needed and then say how many of each item they need for the order.

So when they pick the breakfast menu, it selects all starters, mains and desserts.  Should something need to be edited (sausages changed to vegitarian sausages) the user should be able to overtype what has been populated from the select statement)

When the form is submitted, the order needs to be linked to the current job which is in a field ssm_job.job_id but the changes to the menu items need to be stored somewhere for the current order only.  This obviously needs to be accessile later so further changes can be made if needed.  I am not sure of the best way to go about this as i am trying not to save every item in another database (just trying to be tidy)

Any advise on this would be greatly appreciated.

I have had help on this project in relation to an sql and the background can be found below, the help has been amazing but as this is a very different question i thought i would start a new thread.

 

Kind Regards

Hello everybody, i try to check if the unique field inventar exists or not before i insert new record. if the inventar exits the user should get error message. but i dont know how to do this.   thank you very much for your help. Rafal   here is my code

<?php
include("123.php");
$inventar = $link1->real_escape_string($_POST["inp_inventar"]);
$product = $link1->real_escape_string($_POST["inp_product"]);
$price = $link1->real_escape_string($_POST["inp_price"]);

$link1 = new mysqli("$hoster", "$nameuser", "$password", "$basedata") or die ("Connection Error!"); error_reporting (0);
$check_inventar = mysqli_query($link1, "SELECT inventar FROM products WHERE inventar='$inventar'");
$check_inventar_num = mysqli_num_rows($check_inventar);
if (isset($_POST['inp_submit']) AND $check_inventar_num = 0)
{
$query1 = "INSERT INTO products
(inventar, product, price)
VALUES ('$inventar', '$product', '$price')";
$result1 = $link1->query($query1) or die("Database Error!");
if ($result1 == true)
{
header ( 'Location:insert.php' );
}
}
else { echo "there is already product with same inventar id!"; }
mysqli_close($link1);
?>

Hello,

I'm currently using this code to check for blank fields:

if(isset($_POST['submit']))
{
$emailconfirm = $_POST['emailconfirm'];
$user_message = $_POST['message'];
$name = $_POST['name'];
$visitor_email = $_POST['email'];
if(empty($name)|| empty($visitor_email)|| empty($user_message))
{
$errors .= "<div id='contact_form_errorloc' class='err1'>Some of the above fields have not been filled in.</div><br>";
}

This however, does not check for valid emails, I've found this code:

function is_valid_email($email) {
  $result = TRUE;
  if(!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$", $email)) {
    $result = FALSE;
  }
  return $result;
}

My question was if the above is possible aswell as incorporating the blank field checks.

Many thanks!

Now this one is a bit of a shit head. I am using a really comprehensive class i found on on the web for upload / re-size / crop but i want to be able to override it's error handling and i am not good enough to start modifying the code in the class with out fucking it up.

Firstly i will show you how i have invoked the class.
Code: [Select]
if( isset($_FILES['image'] ) ) {

//Class includes
include("../scrips/php/cms/database.insert.class.php");
include ("../scrips/php/cms/img.upload.resize.crop.class.php.php");


//----------|Start: upload, resize & save
$your_image = new _image;

//----------| Upload orginal image
$your_image->uploadTo = 'uploads/';
$upload = $your_image->upload($_FILES['image']);


//----------| Resize and upload small thumbnail
$your_image->newPath = 'thums/';
$your_image->newWidth = 50;
$your_image->newHeight = 50;
$resized = $your_image->resize();



//----------| Resize and upload medium thumbnail
$your_image->newPath = 'thums2/';
$your_image->newWidth = 100;
$your_image->newHeight = 100;
$resized = $your_image->resize();
//----------| Getting the image name to insert into the database futher on in the code
$name = $resized;
$img_str = explode("/",$name);
$final_img_name = $img_str['1'];

echo "Article has been added!";

//----------------|end

//----------------| Start database insert (class manipulation)
$table = "blog_posts";
$title = "'".$_POST['ArticleTitle']."',";
$img = "'".$final_img_name."',";
$post = "'".$_POST['ArticleBody']."',";
$aurthor_id = "'1',";
$category_id = "'".$_POST['Category']."',";
$date_posted = "NOW()";


$values = array("$title","$img","$post","$aurthor_id","$category_id","$date_posted");
$fields = array('title,','img,','post,','aurthor_id,','category_id,','date_posted');
$obj= new DatabaseInsert;
$obj->DatabaseConnectionRequire();
$obj->ArticleInsert($values,$fields,$table);
//----------------|end
}


As you can see it's fairly basic. What i want to do is before it runs this script and starts including/invoking the class etc, i want to be able to check to see if there is a value been posted from a FILE FORM OBJECT and if there is to proceed with this script, alternatively i want it to execute another code which will handle it in regards to the concept of my page. A simple javascript alert with be ok providing it reloaded the page to it's default state. If any one can help me here i would appreciate it a lot. Thanks
 

I have a register script, and I am wanting to make it so that if the username field contains, lets say "mod", "ass", and more, then it'll return an error and wont let them register.

I want to add a note field and a checkbox to my list/grid page and save this information to a json file using uomptrucknumber as the key. The note information will be information for the whole truck not by order. The check box will let them know that the truck is ready to have paper work printed.

I have not add the note field or checkbox because I did not want to start off wrong.

I have read around and can't seem to find the right coding for what I need on this forum and some other other forums.

I have a contact form (as listed below) and I need 2 locations (Print Name and Title) fields to auto-populate on a separate form (can be a doc, pdf, etc. any form of document which is easiest) and this form can be totally back end and the individual using the form never is going to see the form.

It's going on a contract form, that we would like to auto-populate.

Also is there a simple attachment code so individuals can attach documents to the code?

Stumped!  I have a client who has a form where they upload files to their server: title, two password fields, and the file They have been unable to upload anything over 10m   Small (under 10mb) files work. Larger doesn’t I’ve tracked it down, I think, that the processing page appears to be dropping the form values when the file takes a bit to upload.   I echo’ed the values that are grabbed from the form, and they return empty strings if it takes a while for the file to upload (a large file) - they pass fine if the file is smaller.   I think I've got the php info set correctly, but cannot for the life of me figure out how to adjust the timing out issue, or even where to troubleshoot.   Here's my phpinfo:   Max Requests Per Child: 750 - Keep Alive: off - Max Per Connection: 100 Timeouts Connection: 120 - Keep-Alive: 5     Directive Local Value Master Value allow_call_time_pass_reference Off Off allow_url_fopen On On allow_url_include Off Off always_populate_raw_post_data Off Off arg_separator.input & & arg_separator.output & & asp_tags Off Off auto_append_file no value no value auto_globals_jit On On auto_prepend_file no value no value browscap /etc/browscap.ini /etc/browscap.ini default_charset no value no value default_mimetype text/html text/html define_syslog_variables Off Off disable_classes no value no value disable_functions leak,posix_getpwuid,posix_getpwnam,posix_getgrid,posix_getgrnam,posix_getgroups leak,posix_getpwuid,posix_getpwnam,posix_getgrid,posix_getgrnam,posix_getgroups display_errors Off Off display_startup_errors Off Off doc_root no value no value docref_ext no value no value docref_root no value no value enable_dl Off Off error_append_string no value no value error_log /mnt/Target01/337846/945285/www.dermerrealestate.com/logs/php_errors.log no value error_prepend_string no value no value error_reporting 30711 30711 exit_on_timeout Off Off expose_php Off Off extension_dir /usr/lib64/php/modules /usr/lib64/php/modules file_uploads On On highlight.bg #FFFFFF #FFFFFF highlight.comment #FF8000 #FF8000 highlight.default #0000BB #0000BB highlight.html #000000 #000000 highlight.keyword #007700 #007700 highlight.string #DD0000 #DD0000 html_errors On On ignore_repeated_errors Off Off ignore_repeated_source Off Off ignore_user_abort Off Off implicit_flush Off Off include_path .:/usr/share/pear:/usr/share/php .:/usr/share/pear:/usr/share/php log_errors On On log_errors_max_len 1024 1024 magic_quotes_gpc On On magic_quotes_runtime Off Off magic_quotes_sybase Off Off mail.add_x_header On On mail.force_extra_parameters no value no value mail.log no value no value max_execution_time 30 30 max_file_uploads 20 20 max_input_nesting_level 64 64 max_input_time 60 60 max_input_vars 1000 1000 memory_limit 128M 128M open_basedir no value no value output_buffering no value no value output_handler no value no value post_max_size 8M 8M precision 14 14 realpath_cache_size 4M 4M realpath_cache_ttl 120 120 register_argc_argv On On register_globals Off Off register_long_arrays On On report_memleaks On On report_zend_debug On On request_order no value no value safe_mode Off Off safe_mode_exec_dir no value no value safe_mode_gid Off Off safe_mode_include_dir no value no value sendmail_from no value no value sendmail_path /usr/sbin/sendmail -t -i /usr/sbin/sendmail -t -i serialize_precision 100 100 short_open_tag On On SMTP localhost localhost smtp_port 25 25 sql.safe_mode Off Off track_errors Off Off unserialize_callback_func no value no value upload_max_filesize 8M 8M upload_tmp_dir /tmp /tmp user_dir no value no value user_ini.cache_ttl 300 300 user_ini.filename .user.ini .user.ini variables_order EGPCS EGPCS xmlrpc_error_number 0 0 xmlrpc_errors Off Off y2k_compliance On On zend.enable_gc On On
