使用 Php 我想知道如何从用户那里获取颜色输入并将该颜色设置为页面的背景

Question

I'm curious if I'm on the right track.

<?php
    $color = readline("Enter background: ");
    echo "<div style = 'background-colour:\'$color\' '";

?>

Any help would be appreciated, I'm really struggling with PHP :)

Answer 1

So here we have to separate the problem into 3 parts.

1 -> Get the user input, which should be either HEX, RGB, RGBA wtv...

2 -> Get that value onto a variable so that you can later on dynamically assign it to your HTML tag (body I suppose) and set its background color to the value of that variable.

3 -> Assign the value of the variable to your html tag.

After doing some research, I found this line.

Which mixes, my logic in fewer steps haha, but the logic remains the same.

<?php echo '<input type="hidden" maxlength=100 name="value" id="val" value="'.$myobj->foo.'">';

You just need to change the to and it should work.

Lmk how that goes.
