Avoiding form resubmit in php when pressing f5
I need help on how to prevent the DOUBLE DATA SUBMISSION to mysql database.
This usually occurs when after the submit, user hits REFRESH button.
Whenever I send data using html web forms to handle them in sever side I'd better omit action attribute of a form which explains that the file will be processed by itself and starting from the first line i place server side php scripts. Before sending data I sctrictly check if all fields are filled correctly and then send that data to future processing. Using php script I'll check if web form button which was clicked is not null and then via established connection to mysql execute manipulation queries.
Is using header function to redirect to itself is an optimal way to prevent Double Data Submission???
Haven't you any ideas?
In addition I'll include the code
<?php
include_once '../config.php';
include_once '../functions.php';
if (isset($_POST['bDep'])){
$flt=$_POST['flt'];
$num=$_POST['fltNum'];
$acr=$_POST['acr'];
$city=$_POST['city'];
$fTime=$_POST['fTime'];
$bReg=$_POST['bReg'];
$eReg=$_POST['eReg'];
$acomp=$_POST['aircomp'];
$gate=$_POST['gate'];
$dte=$_POST['data'];
$tm=explode(":",$fTime);
if ($tm[0]<3) $p=1;
else $p=0;
$otmena=$_POST['cancel'];
if ($otmena==1) $stat=4;
else $stat=7;
$sql="INSERT INTO fltdep(FID, FLT, NUM, DEP, TO_FROM, IN_OUT, dte, Stat, BReg, EReg, Gate, AType, ALn, Cir, Hide ) VALUES (0, '$flt', '$num','$fTime', $city,1, '$dte',$stat,'$bReg','$eReg','$gate',$acr,$acomp,$p,0)";
if (mysql_query($sql)){
echo "<p style='text-color:red;text-align:center;'>Успешно добавлена запись № </p>";
}else {
echo "<p style='text-color:red;text-align:center;'>Ощибка при добавлении к базе</p>";
}
unset($_POST['bDep']);
unset($_POST['flt']);
}
?>

Your method (Header redirect after post) is necessary, but insufficient.
Some users press links twice (doubleclick). And your code sometimes might insert the same record twice in this case. You need to write a JavaScript that would disable submit button after first click.

That code can't works. You can't call PHP function using javascript onclick.
For your clarification this code would execute costam() function everytime page is loaded.
Try to change Button1 with:
<input type="submit" id="Button1" name="submit" value="Zatwierdź" style="position:absolute;left:194px;top:164px;width:96px;height:25px;z-index:7;">
Then change php code in:
<?php
if($_GET['submit']){
$imie= $_GET['x1'];
$Nazwisko=$_GET['x2'];
$Numer= $_GET['x3'];
//łączenie
$dane=$imie.", ".$Nazwisko.", ".$Numer;
//dodawanie nowej linii
$popr=$dane." k\n";
//otwieranie, zapisanie, zamknięcie
$plik=fopen("zap.txt", "a");
fputs($plik, $popr);
fclose($plik);
}
This should works, but is not a good approch. Also the page will refresh.
If you're familiar with jQuery:
jQuery.ajax({
type: "POST",
url: 'your_functions_address.php',
dataType: 'json',
data: {functionname: 'add', arguments: [1, 2]},
success: function (obj, textstatus) {
if( !('error' in obj) ) {
yourVariable = obj.result;
}
else {
console.log(obj.error);
}
}
});

A PHP quiz that calculate averages

I'm trying to make a quiz that will show the person who take it the average of the number of answer they got right. For example: if they have 2 right it would display 66%. Can someone please explain to me how I can do something like this.

Use this code:

// If the submit button has been pressed
if (isset($_POST['submit'])) {
// Check answer
if ($_POST['answer'] == 21) { {
$numcorrect++;
}
if ($_POST['answer1'] == 46) {
$numcorrect++;
}
if ($_POST['answer2'] == 2468) {
$numcorrect++;
}
$average = ($numcorrect/3)*100;
echo "<h1>Your Average is $average %</h1>";
}
}
?>
:)

$average=$numcorrect/count ($numcorrect);
echo "<h1>Your Average is ".$average."%</h1>";
You already calculated the average, so put it in the string with the . string concat operator. Additional hint: Check your code, what happens if I don't know any answer?

use value and label in php dropdown

I have this code to pull values and labels from a MySQL DB and populate a drop down box, on change it put the value in a text field, but I want the label not the value.
Any pointers would be good..
<select name="CompanyInternalID" autofocus class="textBox" id="CompanyInternalID" style="width:300px" onchange="document.form1.CompName.value=this.value">
<?php
do {
?>
<option value="<?php echo $row_rsCustomerList['AKA']?>"><?php echo $row_rsCustomerList['CustomerName']?></option>
<?php
} while ($row_rsCustomerList = mysql_fetch_assoc($rsCustomerList));
$rows = mysql_num_rows($rsCustomerList);
if($rows > 0) {
mysql_data_seek($rsCustomerList, 0);
$row_rsCustomerList = mysql_fetch_assoc($rsCustomerList);
}
?>
</select>
<input type="text" name="CompName" class="textBox" style="width:180px" id="CompName" />
Thanks

You can use jQuery to get the selected value and put in the required text field.
Suppose the id of dropdown is "drop" and id of text field is "txt_id" . Now you can use below code:
$("#drop").change(function () {
$("#txt_id").val($(this).val());
});

You can use below code:

$_SESSION not storing values

first my creds:

producing this result

Please do not mind the JS, it is preschool client validation just to move forward.
Any help would be greatly appreciated.

Give your login form a name, and then in your JavaScript validation function, instead of window.location, do a document.forms['yourformname'].submit().

I think your Javascript validation is actually what's causing the issue.
You're setting the session variable in Login.php using the POST request, but no POST is actually being sent to Login.php since your Javascript is redirecting to Home.php once the form is considered valid. You need to submit the form at some point in the process, so you actually get some POST values which you'll use to populate your SESSION variables.
If you want to keep your Javascript validation, maybe have a look at submit() : http://www.w3schools.com/jsref/met_form_submit.asp
You'll have to set a correct action property on your form before submitting it.

So heres a fix that seems to be working

PHP Ajax Realtime autosave Fwrite to config.txt

Im trying to figure this out but its really getting to me 2nd all day on trying code and searching ...
Trying to see guidance if i am getting to the right direction with ajax and autosaving when a user performs an action on the button (BUT i do need to have a config.txt)
Because its more of an Active running application for enabling/disabling an action with custom options needed on the fly.
Trying to (ON page load ) read file config.txt (and auto change the values on the form to what was read from config.txt like a 2 way async (Without reloading the page)
config.txt
active=1
email=1
markets=chi,nyc,orl,sfo
timer=15
emailaddress=test#gmail.com
logviewer=1
so Being that markets has option to add 1 or more i need to post with commas ...
Thus when active=1 is enabled theres a bash script in the background that will be executed based on the selection of the active (when the user checks the box IN REALTIME) ... (onclick)

PHP, A popular general-purpose scripting language that is especially suited to web development.

searching a solution to get/post DOUBLE DATA SUBMISSION [duplicate] - php

Your method (Header redirect after post) is necessary, but insufficient. Some users press links twice (doubleclick). And your code sometimes might insert the same record twice in this case. You need to write a JavaScript that would disable submit button after first click.
