Insert image into coordinates

Hi,

it would be my advice to php echo to my positions, which can be obtained by clicking on the image, display the red cross?

The coordinates are transmitting in this format:

[code=html]http://localhost/capture_the_position_of_the seats/?image.x=432&image.y=448[/code]

Script:

[code=php]
<?php

if(isset($_GET[“image_x”]))

file_put_contents(“soubor.txt”,$_GET[“image_x”].”,”.$_GET[“image_y”].”n”,FILE_APPEND);

echo “<img src=”http://www.stylovedarky.cz/inshop/layout/img/krizek2.gif” />”;

?>[/code]

Also in #PHP _↴
