PHP - Validate That All Fields In A Form Have A Value
Hello. So I already know an extremely elementary way to check to see if a form field is blank using PHP. For example:
Code: [Select] if ($subject == "") The question I have is, is there a way to have php check every field in a form to make sure it has some sort of value? I want to create an 'if' statement which basically says, "If all form fields have something filled in, then do this" For example Code: [Select] if ($subject == "any value") & ($name == "any value") & ($comment == "any value") Not sure if that makes sense. Any help would be greatly appreciated!!! Similar TutorialsHello, i need to validate 200 input fields if they are not empty, i have the following code where i'm stuck and i'm missing something any help is appreciated Code: [Select] if($_SERVER['REQUEST_METHOD'] == 'POST') { //print_r($_POST); foreach ($_POST as $value) { if (empty($value)){ echo 'empty'; } else { echo 'notempty'; } } } I need to validate the POST fields below except a few hidden inputs like User_id & category: They are not huge but i would not like to write for each a line of code like if(empty($_popst['field'])) ... How can simplify this by checking only if they are empty and display a message that lists all fields that were not filled? Code: [Select] array('user_id'=>$data['Id'], 'surname'=>$_POST['surname'], 'firstname'=>$_POST['firstname'], 'middlename'=>$_POST['middlename'], 'id_number'=>$_POST['id_number'], 'pin_number'=>$_POST['pin_number'], 'street'=>$_POST['street'], 'estate'=>$_POST['estate'], 'hse_number'=>$_POST['hse_number'], 'town'=>$_POST['town'], 'tele'=>$_POST['tele'], 'mobi'=>$_POST['mobi'], 'work_street'=>$_POST['work_street'], 'work_building'=>$_POST['work_building'], 'company'=>$_POST['company'], 'work_town'=>$_POST['work_town'], 'work_tele'=>$_POST['work_tele'], 'work_fax'=>$_POST['work_fax'], 'cont_surname'=>$_POST['cont_surname'], 'cont_firstname'=>$_POST['cont_firstname'], 'cont_middlename'=>$_POST['cont_middlename'], 'cont_street'=>$_POST['cont_street'], 'cont_building'=>$_POST['cont_building'], 'cont_company'=>$_POST['cont_company'], 'cont_home_tele'=>$_POST['cont_home_tele'], 'cont_office_tele'=>$_POST['cont_office_tele'], 'cont_mobi'=>$_POST['cont_mobi']); Hi I'm currently having a problem with my form. Users submit an empty field into the database and the next time another user tries to enter it just says username has been taken. I need some help on how to confirm that the username and email field isnt empty when inserted and that the email address is in the correct format.

Is jquery/Ajax better than real/raw PHP for form validation ?! What if JavaScript is turned off on the browser?! why after someone refreshing a page on the browser, the variables used to echo error after invalid data is being submitted will return the undefined variables error?! And how to handle form validation including an empty form field, maximum amount of value entered and so on How do I make email, name and phone required fields? thanks in advance <?php $email = $_POST['email']; $name = trim($_POST['name']); $phone = trim($_POST['phone']); $time = trim($_POST['time']); $zipcode = trim($_POST['zipcode']); $date = trim($_POST['date']); $EmailTo = "myemail@somedomain.com"; $Subject = "form"; /// Add a subject $Body = ""; $Body .= "Full name:\n$name\n\n"; $Body .= "Primary phone:\n$phone\n\n"; $Body .= "time:\n$time\n\n"; $Body .= "Zip code:\n$zipcode\n\n"; $Body .= "date:\n$date\n\n"; if($Subject == NULL) {$Subject = "From $EmailFrom";} $success = mail($EmailTo, $Subject, $Body, "From: <$EmailFrom>"); if ($success){ header ('Location: confirm.html');} else{ echo "Error! Your e-mail was not sent!";} ?> how can i validate if email is being entered correctly in a form? i have the following code Code: [Select] <?php if(isset($_POST['Submit'])){ //NEED TO CHECK IF FIELDS ARE FILLED IN if( empty($_POST['email'])){ header("Location:Messages.php?msg=12"); exit(); } if( empty($_POST['name'])){ header("Location:Messages.php?msg=3"); exit(); } if( empty($_POST['pw1']) && (empty($_POST['pw2']))){ header( "Location:Messages.php?msg=4" ); exit(); } $name=$_POST['name']; $email=$_POST['email']; $pw1=$_POST['pw1']; $pw2=$_POST['pw2']; if("$pw1" !== "$pw2" ){ header( "Location:Messages.php?msg=5" ); exit(); } $ip = $_SERVER['REMOTE_ADDR']; //connect to the db server , check if uname exist include('config.php'); $query1=("Select * from user where email='$email'"); $result1= mysql_query($query1); $num1=mysql_num_rows($result1); if ($num1 > 0) {//Email already been used header( "Location:Messages.php?msg=11" ); exit(); }else{ $query=("Select * from user where uname='$name'"); $result= mysql_query($query); $num=mysql_num_rows($result); if ($num > 0) {//Username already exist header( "Location:Messages.php?msg=6" ); exit(); }else{ //if username does not exist insert user details $query=( "INSERT INTO user (uname, pw,email,date_joined,ip,level) VALUES ('$name','$pw1','$email',NOW(),'$ip','Normal')"); if (@mysql_query ($query)) { header("location:login.php?reg=1"); exit; } } } mysql_close(); } ?> Hey Everyone, Im having trouble with this code, i'm trying to use preg_match to display an error when someone inputs their email and it doesnt have a specific domain (like for example yahoo.com). My logic is to use it as a filter, if the input doesnt have the word '@yahoo.com' it will show the error. What am I doing wrong? Code: [Select] if(preg_match("/^[a-zA-Z]\w+(\.\w+)*\@\yahoo.com", $data['email']) === 0) $err .= "• $lang[ERROR_DOMAIN]<br>"; Any help will be greatly appreciated. Thanks. - STG I want to make the form so only people with a specific email address can sign up to the site. So for example their ending email address was.... @something.apple.biz.com .. but to be accepted into the site, the email HAS to end with apple.biz.com. How could you validate it so it matches something specific like this. Here is my code at the moment which just checks that their is at least one . after the @ for it to be an acceptable email. If anyone could say what else to add to do this would be great if($email != '' && $register){ $emailcheck = explode("@", $email); $sql = "SELECT email FROM member WHERE email='$email'"; $query = mysql_query($sql); $emails = mysql_num_rows($query); if($emails != 0 ){ $alert .= '<p class="alert" style="clear:both;">That email address has already been registered</p>'; $register = false; }elseif(count($emailcheck) != 2){ $alert .= '<p class="alert" style="clear:both;">Please enter a valid email address</p>'; $register = false; }elseif(count($emailcheck) == 2){ $emailchecktwo = explode(".", $emailcheck[1]); if(count($emailchecktwo) < 2){ $alert .= '<p class="alert" style="clear:both;">Please enter a valid email address</p>'; $register = false; } } } Hi- the code below lets me upload a CSV file to my database if I have 1 field in my database and 1 column in my CSV.

How do I go about doing this?????? I have got another of those problems that should be easy to solve but I cannot get my head round it! I have a form to enter data into a table and one of the fields can be left blank. However, I'd data is entered in the field it can be a Zero. This is leaving me a problem as I cannot find a way to get the script to insert NULL if the field is blank but actually put the Zero in if that is what is entered. I have tried several permutations of nested if's using empty or isset, but whatever I try, the same result is inserted in both scenarios. The arguments I need to pass are...... If field is empty INSERT null If field is 0 INSERT 0 If field is not empty and not 0 INSERT field Thanks in advance for any suggestions. Steve Is there anything wrong (or insecure) with using hidden form fields? I am working on a page where the user can choose one of 4 different subscription options. The approach I was going to use is to have a separate form for each plan, and when the user chooses one, submit a hidden form value so my script knows which subscription plan to grab out of the database. Thoughts? Good morning, I am a beginner at PHP, but trying to write a simple script to use at work and currently stuck on one part, looking for some advice! I have a simple form here > http://jmdostal.com/route2.php (Feel free to use it to test), that returns data on the next page, in a format such as : Jose F - Jose A - 285 Brenda L [Delivery] [Dallas] - Items Job 2 [Pickup] [Arlington] - Items [] [] - [] [] - [] [] - [] [] - [] [] - Gustavo - +1 - 284/pickup Jody W [Delivery] [Keller] - Items [] [] - [] [] - [] [] - [] [] - [] [] - [] [] - My question is how can I get it not to show the fields that are empty, so I dont have a bunch of lines with [] [] - formatting Here is my coding you can view here > http://jmdostal.com/code.txt A friend had suggested to me trying to use isset , so I tried it on a few lines, such as : if(isset($_POST['items14'])){ $items14 = "- ". Trim(stripslashes($_POST['items14'])); } But it didnt seem to change anything. Im sure this is something simply, Any suggestions are appreciated! Thanks ! Hello, A named field in an html form e.g. <input type="text" name="time"> is accessed as $_GET['time'] or $_POST['time'] by the processing script. What about an unnamed field like the one below: <input type="text" value="" id="1" /> How do I harvest this field's input as a variable from my php processing script?

Thanks I have html form that looks like: <form method="post" action="?a=up"> ...some mysql query... while ($i = mysql_fetch_array($result)) { <input name="name[]" type="text" value="<?=$i['name'];?>" /> <input name="years[]" type="text" value="<?=abs($age);?>"/> <input name="to[]" type="checkbox" value="<?=$i['id'];?>" /> } <input name="" type="submit" value="go" /> </form> The problem I have is that I can not get the values of the form fields such as "name" and "years". I can only get a list of the ids (value of "to" checkbox). The php code looks like: $cnt = 0; for($p = 0; $p <= (sizeof($to)-1); $p++) { echo $to[$p].$name[$p].$years[$p]"<br>"; $cnt++; } $tm = array($cnt); What I'm doing wrong? Hello everyone I need your assitance a great deal, so I have a form which i submitted to a php file throug ajax and jquery. It is working A ok but I want to be able to submit it with javascript instead, so i don't load any lib. And it is now a problem. The method I use to get the form field names and values in jquery is so simple and dynamic hence if changes are made on the html form i don't have to edit my jquery file to effect the change ie in respect to changing the name of the fields or adding more fields. But I don't know to archieve this using javascript. So i want to post my jquery script, for you all my mighty programmers to assist me get a javascript Clone for me, thank you very much for Helping Jquery file $("form.ajax").on("submit", function(){ var that= $(this); that.find('[name]').each(function(index,value){ var that = $(this), name =that.attr('name'), value =that.val(); data[name]=value; }); return false;}); Now the above code is just my major focus of the script. What it does is that select the form with an ajax class attribute and run a function after the user submits the form. The var that get reference to the above form throug the (this) reference. Next i use find fuction to look through out the open and close of our form.ajax form for any element that has the name attribute and set it into array using the .each(function (index,value){}) this is my main focus how to ilterate through the form looking for name attribute and set my finding into array using javascript. The next that var reference to the find statement and then we steal the name attribute and value from our findings and set an array called data with the stolen name variable as its index n value attribute as its value. Thank you once more my aim again is with the find and array setting statement. |
