提交PHP后禁用按钮 [英] Disable button after submit PHP

问题描述

 <？php $ b $这个代码在提交时会从数组中产生随机数。 b 
 if（isset（$ _ POST ['roll']））{
 $ randarray = array（1，2，3，4，5，6，7，8，9，10）; 
 $ randselect = array_rand（$ randarray）; 
 $ nr = $ randarray [$ randselect]; 
 echo'< p class =btn btn-info>分支：'。 $ NR。 < / p为H.; 
} 
 
？> 
 
< form action =＃method =post> 
< button type =submitclass =btn btn-defaultname =roll> Roll Branch< / button> 
< / form> 
  

我想要做的是在表单提交后，按钮将被禁用。任何想法？

解决方案

如果按下按钮，只需添加 disabled 例如

 < button type =submitclass =btn btn-defaultname =roll<？php echo isset（$ _ POST [roll]）？ disabled：;？>>滚动分支< /按钮> 
  

I have this code that when submitted, it generates random number from the array.

<?php 

    if(isset($_POST['roll'])) {
        $randarray = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);
        $randselect = array_rand($randarray);
        $nr = $randarray[$randselect];
        echo '<p class="btn btn-info"> Branch: '. $nr. '</p>'; 
    }

?>

<form action="#" method="post">
    <button type="submit" class="btn btn-default" name="roll">Roll Branch </button> 
</form>

What I wanted to do is after the form was submitted, the button will be disabled. Any thoughts?

解决方案

Just add disabled if the button is pressed, e.g.

<button type="submit" class="btn btn-default" name="roll" <?php echo isset($_POST["roll"]) ? "disabled" : "";?>>Roll Branch </button>
