Another Parse error: syntax error, unexpected T_BOOLEAN_AND

[cizm]

Please someone can help me?

I got the error message Parse error: syntax error, unexpected T_BOOLEAN_AND

Error message refers to the line:
$db->delete("weblog_postmonitor","post_id=".$post->id." AND user_id=".$user->id);

that seems to be correct, in the following piece of code:

if ($user) {
	$loc = exponent_core_makeLocation('weblogmodule', $_GET['src']);
	$weblog = $db->selectObject("weblogmodule_config","location_data=".serialize($loc));
	$post = $db->selectObject("weblog_post","src=".$_GET['src']);
	if ($post) {
    $existing = $db->selectObject("weblog_postmonitor","post_id=".$post->id." AND user_id=".$user->id);
		if ($existing && $_GET['monitor'] == 1 || !$existing && $_GET['monitor'] == 0) {
			// No change
			exponent_flow_redirect();
		} else {
			if ($_GET['monitor'] == 0) {
				$db->delete("weblog_postmonitor","post_id=".$post->id." AND user_id=".$user->id);
				exponent_flow_redirect();
			} else {

The line number referenced frequently does not match the line the error occurred.
If you are using a code editor with text colouring you might see a highlight indicating a missing brace or bracket
- you may need to select each brace till one shows it is missing its other half

Thank you very much, cretaceous. I tried several alternatives of parentesis, braces and brackets without success.
A possibility would be a missing " before user_id in the command sequence "post_id=".$post->id." AND user_id=".$user->id, but it dit not work either.

Paste in a bigger chunk of the code so we have the whole of the :
if ($user) { ... }
code

The line you mention has an even number of " quotes- so it's fine - that's one way to do a quick check.
