使用带有输入和提交按钮的while循环在php中回显他们输入的次数

Question

I figured out my PHP script using a while loop, now I want to incorporate an input and submit button to have a user pick a date of the month from 1-31 and when they input a date I will have PHP echo out "hello" that many times they entered.

I just cant figure out how to tie it in with an input and submit button so as not to make my code hard coded, I want to make it dynamic.

Here is my code:

<form method="post" action="<?php echo $_SERVER['PHP_SELF'];?>">
   Enter the date of the month: <input type = "text" name ="Enter the date of the month">
   <input type = "submit" name="submitDate">
</form>

<?php
    $x = 1;
    while($x<=31){
        echo "hello<br>";
        $x++;
    }
?>

Answer 1

your gonna need isset function of php to accept your html user input.

HTML

Enter the date of the month: <input type = "text" name ="date">

PHP

    if(isset($_REQUEST['submitDate'])) {
     $x = $_POST['date'];
    }

then you can use $x in your while loop to output hello.
