In IE it shows the object (a second dropdown) but without the value of q the next query won't work.

Greaser9780 Posted March 5, 2007 Author Share Posted March 5, 2007 Well I can't understand why in firefox value of q gets passed from the first dropdown to the second. The first dropdown has six items q would be the value of that. When that gets past to the second dropdown a query uses q to determine what to display in the next dropdown.

fenway Posted March 5, 2007 Share Posted March 5, 2007 What I'd like to see is the line where you assign the value of q. Link to comment https://forums.phpfreaks.com/topic/41260-solved-why-wont-the-value-of-q-get-passed-in-ie/#findComment-199953 Share on other sites More sharing options...
Greaser9780 Posted March 6, 2007 Author Share Posted March 6, 2007 First select page: <html> <head> <script src="selectuser.js"></script> </head> <body> <div align="center"> <form> <select name="users" onchange="showUser(this.value)"> <option>QB <option>WR <option>RB <option>TE <option>K <option>DF </select> </form> </div> <div id="txtHint"> </div> </BODY> </html> You already have the .js script And here is the second dropdown page: <?php $q=$_GET['q']; include("db.php"); $sql="SELECT name FROM players WHERE position='".$q."' ORDER BY name ASC"; $result = mysql_query($sql); ?> <html> <head> </head> <body> <form action="select.php" method="post"> Comment:<input type='text' name='com' maxlength='80'><br> <select name="playername"> <?php while($row = mysql_fetch_array($result)) { echo "<option value='" . $row['name'] . "'>" . $row['name']."</option>" ; } ?> </select> <input type="submit" name="submit" value="select"> </form> </body> </html> I thought the showuser function used at onchange sent (this.value) to the .js file as the (str) in the function description and was included with the url as url=url+"?q="+str . So I figured the value of q was equal to the choice that the user made. If I am wrong in this please chow me where I went wrong and give an opinion of how to fix it.

fenway Posted March 7, 2007 Share Posted March 7, 2007 OK, that makes sense, I was confused about q because it was both a variable and a string literal. Are you sure that if you alert the url variable after the assignment it's different in the two browsers?

Greaser9780 Posted March 8, 2007 Author Share Posted March 8, 2007 The problem I can see is that in IE the value of q is not read by the next script. It doesn't make sense to me as to why it won't. I currently get no object type of error. The only error I do get is a small error symbol at the bottom of my browser. A little yellow ! in a triangle. I ran it in firefox. It works and I get no errors in the console other than css errors and that's only due to where the files currently reside. I can't even echo $q in IE so I know the problem is that IE won't get the value. It does however display the next dropbox like it's supposed to. It's just empty because I use $q to pull data with a query.

Greaser9780 Posted March 9, 2007 Author Share Posted March 9, 2007 It works in netscape as well with no errors. I tried an alert to show the object. I get the same in netscape and firefox XMLHttpRequest as object. But when I run it in IE I just get "object". Is it possibly my browser settings?

fenway Posted March 9, 2007 Share Posted March 9, 2007 Yeah, I've run into similar issues with FF "making up" attributes as it goes along... often, IE is guilty of this, but it won't give you a value is there's no value... imagine that.

Greaser9780 Posted March 9, 2007 Author Share Posted March 9, 2007 It's kind of ironic. In my second dropdown I list a value for each one.
