wall posting issue

[fife]

I have this awesome little script that I have to configure.  My php is limited but I can get by, my javascripting is very limited to say the least but I can see whats wrong with the script.

 

ok first I will post some of the orginal javascript and the query that it runs.....

 

<script type="text/javascript"> 

// <![CDATA[	

$(document).ready(function(){	

	$('#shareButton').click(function(){

		var a = $("#watermark").val();
		if(a != "What's on your mind?")
		{
			$.post("posts.php?value="+a, {

			}, function(response){

				$('#posting').prepend($(response).fadeIn('slow'));
				$("#watermark").val("What's on your mind?");
			});
		}
	});	

 

next the form itself......

 

<form action="" method="post" name="postsForm">

	<div class="UIComposer_Box">

	<span class="w">
	<textarea class="input" id="watermark" name="watermark" style="height:20px" cols="60"></textarea>
	</span>

		<br clear="all" />

		<div align="left" style="height:30px; padding:10px 5px;">

			    
			 
			</span>
			<a id="shareButton" style="float:left" class="smallbutton Detail"> Share</a>

		</div>

	</div>

	</form>

 

now the php which is in an external sheet called posts.php    .........

 

<?php
include('dbcon.php');
function checkValues($value)
{
	 $value = trim($value); 

	if (get_magic_quotes_gpc()) {
		$value = stripslashes($value);

	}

	 $value = strtr($value,array_flip(get_html_translation_table(HTML_ENTITIES)));

	 $value = strip_tags($value);
	$value = mysql_real_escape_string($value);
	$value = htmlspecialchars ($value);

	return $value;

}	

function clickable_link($text = '')
{
	$text = preg_replace('#(script|about|applet|activex|chrome):#is', "\\1:", $text);
	$ret = ' ' . $text;
	$ret = preg_replace("#(^|[\n ])([\w]+?://[\w\#$%&~/.\-;:=,?@\[\]+]*)#is", "\\1<a href=\"\\2\" target=\"_blank\">\\2</a>", $ret);

	$ret = preg_replace("#(^|[\n ])((www|ftp)\.[\w\#$%&~/.\-;:=,?@\[\]+]*)#is", "\\1<a href=\"http://\\2\" target=\"_blank\">\\2</a>", $ret);
	$ret = preg_replace("#(^|[\n ])([a-z0-9&\-_.]+?)@([\w\-]+\.([\w\-\.]+\.)*[\w]+)#i", "\\1<a href=\"mailto:\\2@\\3\">\\2@\\3</a>", $ret);
	$ret = substr($ret, 1);
	return $ret;
}

$next_records = 10;
$show_more_button = 0;
if(checkValues($_REQUEST['value']))
{
	$userip = $_SERVER['REMOTE_ADDR'];
	echo "INSERT INTO facebook_posts (post,f_name,userip,date_created) VALUES('".checkValues($_REQUEST['value'])."','".danny."','".$userip."','".strtotime(date("Y-m-d H:i:s"))."')";

	mysql_query("INSERT INTO facebook_posts (post,f_name,userip,date_created) VALUES('".checkValues($_REQUEST['value'])."','".danny."','".$userip."','".strtotime(date("Y-m-d H:i:s"))."')");

	$result = mysql_query("SELECT *,
	UNIX_TIMESTAMP() - date_created AS TimeSpent FROM facebook_posts order by p_id desc limit 1");

}


//etc

 

In the php section in the values there is this "danny" for the f_name

 

The issue is simple. Instead of danny i want $User['memberID'].  The problem I have is I dont know how to add the row to the javascript at the beginning to make it work.  The best I have is this......

 

<script type="text/javascript"> 

// <![CDATA[	

$(document).ready(function(){	

	$('#shareButton').click(function(){

		var a = $("#watermark").val();

		var b = $("<?php echo $User['memberID']; ?>").val();



		if(a != "What's on your mind?")
		{
			$.post("posts.php?value="+a+"&mem="+b, {

			}, function(response){

				$('#posting').prepend($(response).fadeIn('slow'));
				$("#watermark").val("What's on your mind?");
			});
		}
	});	
//etc

 

but this is not working.  I would really appreciate some help on this as im all out of ideas.  I would love this feature or one similar to work within my site. Thank you

var a = $("#watermark").val();
var b = $("<?php echo $User['memberID']; ?>").val();

 

$(..) is a jQuery selector. The top line here passes "#watermark", which is referencing the element with the #ID of "watermark". The method .val() is available because the object that is created has a .value property (.val() also has some more advanced capabilities, but that's for another day).

 

All you need to do is store the value of $User['memberID'] within a normal JavaScript variable:

 

var b = '<?php echo $User['memberID']; ?>';

I wonder what alert(b) would output

fife, if this solves your issue please mark as solved, which would make you a cool person

Probably 'undefined', as there's no .value property of a string. jQuery isn't about string operations anyway, it's about "document traversing, event handling, animating, and Ajax interactions". It doesn't replace standard JavaScript objects like Date, Number, String, etc.

[fife]

is it just me or has the mark as solved button disappeared?  This issue was solved

The forums were upgraded not too long ago, and the solved button hasn't been added back yet.
