I have a loop which generates a couple of fields which could be field in. I want to POST all the values from these fields into another php page.
The first page:
for ($i = 1; $i <= 10; $i++) {
print "
<form action='2.php' method='post' id='test_form'>
<input name='value-$i' type='text' />
<input id='send' name='send' type='submit' value='Sent' />
</form>
";
}
The second page:
while ( ) {
$valuer= $_POST['value'];
}
<input name='value[$i]' type='text' />
^--^---- note the []
Then
$fifth_value = $_POST['value'][5];

for example, I receive two inputs value1 and value2 and I want this input for different functions. Like addition, subtraction and multiplication.
my code
<?php
$x = $_POST['fnum'];
$y = $_POST['snum'];
if (isset($_POST['add'])) {
$sum = $x + $y;
echo "Result:<input type='text' value='$sum'/>";
}
if (isset($_POST['sub'])) {
$sub = $x - $y;
echo "Result:<input type='text' value='$sub'/>";
}
if (isset($_POST['mul'])) {
$mul = $x * $y;
echo "Result:<input type='text' value='$mul'/>";
}
<body>
<form method="post">
Enter first number <input type="text" name="fnum" />
<hr />
Enter second number <input type="text" name="snum" />
<hr />
<input type="submit" name="add" value="ADD" />
<input type="submit" name="sub" value="Subtract" />
<input type="submit" name="mul" value="Multiply" />
</form>
</body>
In this it is asking me to feed input for each operation separately
Good, Just use the posted value in your form input like -
Enter first number <input type="text" name="fnum" value="<?php echo #$_POST['fnum'];?>"/><hr/>
Enter second number <input type="text" name="snum" value="<?php echo #$_POST['snum'];?>"/><hr/>
So that user don't need to put the same value again and when press the other buttons the form will automatically submit with the previous values.
Note: Remember, you need to check all the posted value is set or not and use proper conditions of POST method. Have a look at the given example of your problem as solution, I give it here to give you a proper guide.
Example:
<?php
$x = 0;
$y = 0;
if(isset($_POST['submit'])) {
$x = $_POST['fnum'];
$y = $_POST['snum'];
$operator = "";
if($_POST['submit'] == 'ADD') {
$operator = "+";
} elseif($_POST['submit'] == 'Subtract') {
$operator = "-";
} elseif($_POST['submit'] == 'Multiply') {
$operator = "*";
}
$result = $x . $operator . $y;
}?>
Your form will be-
<form method="post">
Enter first number <input type="text" name="fnum" value="<?php echo $x;?>"/><hr/>
Enter second number <input type="text" name="snum" value="<?php echo $y;?>"/><hr/>
<input type="submit" name="submit" value="ADD"/>
<input type="submit" name="submit" value="Subtract"/>
<input type="submit" name="submit" value="Multiply"/>
</form>
Result:
<input type='text' value='<?php echo (isset($result) ? $result : "-";)?>'/>
i want make a view of array, in the first i need fill length of array for first form (this for how much is show) and then i use that to fill value of array then i show that.
<form method="POST" action="prak_9_1.php">
input length of array <input type="text" name="bilangan">
<input type="submit" value="Hasil">
second code is different file
<?php
$bilangan = $_POST['bilangan'];
$bil = $bilangan;
$array = array();
$n = 0;
?>
<form method="POST" action="prak_9_1.php">
<?php
for ($i=0; $i < $bilangan ; $i++) {
echo "input value of array : <input type='text' name='nilai_".$i."'><br>";
}
?>
<input type="submit" value="Hasil">
</form>
<?php
for ($i=0; $i < $bil ; $i++) {
$array[$n] = $_POST['nilai_'.$i];
$n++;
}
print_r($array);?>
sorry if my english is bad... thanks for ur helps...
first file :
<form method="POST" action="second.php">
input length of array <input type="text" name="bilangan">
<input type="submit" value="Hasil">
</form>
and second file :
<?php
if (isset($_POST['bilangan'])) {
echo '<form method="POST">';
for ($i = 0; $i <= $_POST['bilangan']; $i++) {
echo "input value of array : <input type='text' name='nilai[]'><br>";
}
echo '<input type="submit" value="Hasil">';
echo '</form>';
}
if (isset($_POST['nilai'])) {
print_r($_POST['nilai']);
}
?>
In my first page I have this code:
$number="1234567891";
$str="456";
echo "<form action='edit.php' method='POST'><input type='hidden' name='msg' value='$message' />
<input type='hidden' name='text' value='$number' />
<input type='hidden' name='edit' value='$str' />
<input type='submit' name='chedit' value='Go' style='position:relative; top:25px; left: 50%;'>
</form>";
In my edit.php I have this code:
<form action="#" method="POST">
Edit Number
<input type="text" name="change" value="$mumu"/>
<input type="submit" name="pch" value="Change"/>
</form>
<?php
if (isset($_POST["chedit"]))
{
$suj = $_POST["msg"];
$text = $_POST["text"];
$mumu =$_POST["edit"];
if(isset($_POST["pch"]))
{
$change = $_POST["change"];
$obinna = str_replace("$change","$mumu","$text");
echo $obinna;
}
}
?>
My problem is that whenever I put a new text in new form and click submit to edit a character in the old string submitted line the page refreshes and no result is output. Please can anybody sort this out?
// try this ..
if (isset($_POST["chedit"]))
{
$suj = $_POST["msg"];
$text = $_POST["text"];
$mumu =$_POST["edit"];
if(isset($_POST["pch"]))
{
$change = $_POST["change"];
//456 , //555(post value) , //(your text)12345678910
// $obinna = str_replace("Set old value you change in text","set new value you want to set in text ","your orignal text ");
$obinna = str_replace("$mumu","$change","$text");
echo $obinna;
}
}
echo '<form action="#" method="POST">
Edit Number
<input type="text" name="change" value="" placeholder="Change"/>
<input type="text" name="edit" value="" placeholder="Edit"/>
<input type="submit" name="pch" value="Submit"/>
</form>'

I want a calculator with my PHP code that adds values with one after one with submit button.like when I input a number then submit it and show it on the page then and input other, it should add previous number.and then enter another then submit.like these, numbers are adding with one another after submitting.
<?php
session_start();
?>
<?php
error_reporting(0);
?>
<html>
<title>adding input single values</title>
<body>
<form method="post">
<input type="text" name='number' method="post"/>
<input type="submit" />
</form>
<?php
if(!isset($_POST['number']))
{
}
else
{
$sum += $_POST['number'];
echo ++$sum;
}
?>
</body>
</html>
here is the output
You could use a hidden field instead of storing in the session.
<input type="text" name='number' method="post"/>
<?php
if(!isset($_POST['number'])) {
echo "<input type='hidden' name='prev_number' value=0 />";
} else {
$sum = $_POST['number'] + $_POST['prev_number'];
echo "<input type='hidden' name='prev_number' value=" . $sum . " />";
echo $sum;
}
?>
<input type="submit" />
</form>
<?php
if(!isset($_POST['number'])) {
// ...
}
else {
$_SESSION['number'] = isset($_SESSION['number']) ? $_SESSION['number'] : '';
$_SESSION['number'] += $_POST['number'];
echo $_SESSION['number'];
}
I'd like that the variable $order is increase by 1 every time I push the submit button.
(The name of the page is study.php so every time I push the button the page is refreshed):
<?php
$order = $_GET['number'];
echo "<form action='study.php' method='GET'>
<input type='hidden' name='number' value='$order++' />
<input class='big_b' type='submit' value='next' />
</form>";
echo "$order";
?>
The first time 1 push the button $order is 1, the second 2, the third is 3 ... etc
Thanks for your help!
EDIT: SOLVED
<?php
session_start();
if(empty($_SESSION['count'])) $_SESSION['count'] = 0;
$order = $_SESSION['count']+1;
$_SESSION['count'] = $order;
echo "<form action='study.php' method='GET'>
<input class='big_b' type='submit' value='next' />
</form>";
echo "$order";
?>
How you currently have it, is that it will increment on each page refresh regardless whether button was clicked or not, do you need it only to increment if the button is pressed?
<?php
session_start();
// Reset to 1
if(isset($_POST['reset'])){unset($_SESSION['number']);}
// Set or increment session number only if button is clicked.
if(empty($_SESSION['number'])){
$_SESSION['number']=1;
}elseif(isset($_POST['next'])){
$_SESSION['number']++;
}
echo '
<form action="" method="POST">
<input class="big_b" type="submit" name="next" value="Next" />
<input type="submit" name="reset" value="Reset" />
</form>';
echo $_SESSION['number'];
?>
<?php
session_start();
if(empty($_SESSION['order'])){
$_SESSION['order'] = 1;
}
echo "<form action='study.php' method='GET'>
<input type='hidden' name='number' value='".$_SESSION['order']++."' />
<input class='big_b' type='submit' value='next' />
</form>";
echo $_SESSION['order'];
?>
You need to put $order++ outside of the quotation marks to make an operation (incrementing by 1). Here's the code:
<?php
$order = $_GET['number'];
echo "<form action='study.php' method='GET'>
<input type='hidden' name='number' value='".$order++."' />
<input class='big_b' type='submit' value='next' />
</form>";
echo "$order";
?>
