Passing variables from Jquery to PHP
I have tried everythinng anmad cannot get this prograam to work. This is a chess program. When a user double clicks on a square on the board, the cell should be added to the form in the move_to/move_from variable.
Here are code snippits:
<?php
$results = array(array("Br", "Bn", "Bb", "Bq", "Bk", "Bb", "Bn", "Br"),array("Bp", "Bp", "Bp", "Bp", "Bp", "Bp", "Bp", "Bp"),
array("", "", "", "", "", "", "", ""),array("", "", "", "", "", "", "", ""),array("", "", "", "", "", "", "", ""),
array("", "", "", "", "", "", "", ""),array("Wp", "Wp", "Wp", "Wp", "Wp", "Wp", "Wp", "Wp"),
array("Wr", "Wn", "Wb", "Wq", "Wk", "Wb", "Wn", "Wr"));
?>

<td class="d1" id="g8"> <?php echo $results[0][6];?> </td><td class="a1" id="h8"> <?php echo $results[0][7];?> </td>
</tr>

<script type="text/开发者_C百科javascript">
$(document).ready(function(){
$('.a1').click(function() {

move_from = $(this).attr("id");
$.post('jq_test.php',move_from);
alert(move_from);
});
});
<p><a href="jq_test.php?move_from">x</a></p>
<?php
echo "this is the variable ";echo $_GET['move_from'];
print_r($_GET);
?>
snip...
<?php
echo <<<HTML
<form method="post" action="jq_test.php">
Move From<input type="text" name="move_from"> </input><br /><br />
Move To <input type="text" name="move_to"></input><br /><br />
<input type="submit" value="Enter Move"></input>
</form>
HTML;
?>
</body>
</html>
Your javascript is using $.post(), but you're retrieving from $_GET in PHP. Switch to $_POST in PHP instead.
