Question

I have a form that is being created dynamically
<form action="addtable.php" method="post" enctype="multipart/form-data" >
<?php
$sql="SELECT * FROM `tracker_item` ";
$result = mysqli_query($con, $sql);
if(mysqli_num_rows($result)>0)
{
while($row = mysqli_fetch_assoc($result))
{ ?>
<input type="text" placeholder="<? echo $row['heading']?>" name="<? echo $row['heading']?>" />
<?}?>
<button type="submit" name="add" alt="Add" value="Add" class="btn blue">Add</button>
</form>
But i a not able to understand how to carry the value of input to the addtable.php page
Can anyone please tell how to submit these values from this form

Answer 1

In your addtable.php, you need to print_r $_POST and see what inputs you're getting.
// addtable.php
echo "<pre>";
print_r($_POST);
print_r($_FILES); // If you're expecting a file input
Also, you should modify your HTML a little:
<form action="addtable.php" method="post" enctype="multipart/form-data" >
<?php
$sql="SELECT * FROM `tracker_item` ";
$result = mysqli_query($con, $sql);
if(mysqli_num_rows($result)>0) {
while($row = mysqli_fetch_assoc($result)) { ?>
<input type="text" placeholder="<? echo $row['heading']?>" name="<? echo $row['heading']?>" />
<? } ?>
<button type="submit" name="add" alt="Add" value="Add" class="btn blue">Add</button> <!--Place submit button outside loop -->
<?php } ?>

Answer 2

I think there is issue in submit button, you looping submit button with same name, try to put submit button out of while loop.

Answer 3

One of the reasons your PHP is not functioning correctly is because your PHP block, is not placed inside of PHP tags.
Your code should look like this:
<form action="addtable.php" method="post" enctype="multipart/form-data" >
<?php // added the PHP tags
$sql="SELECT * FROM `tracker_item` ";
$result = mysqli_query($con, $sql);
if(mysqli_num_rows($result) > 0){
while($row = mysqli_fetch_assoc($result)){
?> // escaped the php tag
<input type="text" placeholder="<?= $row['heading']; ?>" name="<?= $row['heading']; ?>" />
<button type="submit" name="add" alt="Add" value="Add" class="btn blue">Add</button>
<?php
}
}
?>
Notice how I also escaped PHP when I wanted to display any HTML. Of course, you could simply echo these out, but you can do this too! Personal preference, really.
Another little alteration I made was, rather than using <?php echo ... ?> you can simply use <?= $row['...']; ?>. It is faster and cleaner too!

Answer 4

In your addtable.php:
<?php
$inputValue = $_POST['input_name'];
//the $inputValue is the input value that you posted from form.
echo $inputValue;
?>

Answer 5

To receive data in addtable.php you have to get them by name property of inputs in the form. So you have to define the names of inputs or to retrieve them again from db in addtable.php

Answer 6

try this ,
addtable.php
<?php
foreach ($_POST as $key => $value){
echo "Field ".htmlspecialchars($key)." is ".htmlspecialchars($value)."<br>";
}
?>
i hope it will be helpful.

You can create array of heading and access it in php:
<form action="addtable.php" method="post" enctype="multipart/form-data" >
<?php
$sql="SELECT * FROM `tracker_item` ";
$result = mysqli_query($con, $sql);
if(mysqli_num_rows($result)>0)
{
while($row = mysqli_fetch_assoc($result))
{
?>
<input type="text" placeholder="<?php echo $row['heading']; ?>" name="heading[]"> />
<?
}
?>
<button type="submit" name="add" alt="Add" value="Add" class="btn blue">Add</button>
<?php
}
?>
</form>
In addtable.php:
$headingArray = $_POST['heading']; // here you will get all the heading in array format
