View 3 RepliesHave a WAMP setup with Apache, PHP and Mysql service and I�m working on a HTML form which will have two drop-down controls where information is extracted from two tables in my DB.The first drop-down list called (name="sel_ControlArea") will decide what information the second drop-down list will have.So far I have managed to populate them when the page is loaded using PHP but run into problem when I make a change on the first drop-down list.Question one: What is the best/correct way to solve this problem?Is it to load all information into PHP arrays and then translate these to Javascript arrays, or should I go for AJAX, or XML or are there any other better ways ?I have tried to solve this using the first method, put data in a PHP array but run into problem with this data not properly loaded.This is first time for me to pose a question so please let me know if I have left out some important information or if I should describe this problem in a different way.

I have set up my website quite some time ago that has served its purpose very well, however I will now be adding an order form functionality. So far, by reading books and traversing forums, I have been able to develop a page where the user
1.Enters data into the required fields, that is then submitted to a MYSQL database via PHP,
2.Can retrieve orders that are stored in the database,
3.Delete orders that are stored in the database.
I have wamp installed on my computer as the webserver. I have also incorporated two drop down lists that both retrieve their values from tables within the database. The first drop down list retrieves the Australian States that I have stored in a table, and once the submit button is pressed, it stores the State that is selected to a separate table. This drop down list functions as it should. An extract from "From Place an order.php"
<?php
$dbcnx = @mysql_connect('localhost', 'root', 'tingling');
if (!$dbcnx) {
exit('<p>Unable to connect to the ' .
'database server at this time.</p>');
} .....
The second drop down list retrieves product names from a table that contains products and their prices. What I would like to happen, is that when the product is selected from this drop down list, a text box is automatically filled with its corresponding price. I had this drop down list working as per the "States" drop down list, but could not get it to auto populate the text field. I got some assistance from a friend and was able to get the text box to auto populate with its corresponding price, however when the page was submitted to the database, the "id" number of the product name from the drop down list was stored, and not the product name.
<select name="productSelection" onchange = "getProductDetails(this)">
<option selected value="1product">Select Product</option>
<?php
$products1 = @mysql_query('SELECT * FROM products');
if (!$products1) {
exit('<p>Unable to obtain author list from the database.</p>'); .....

I have 3 ASP list boxes. I would like to populate the second list box based on the selection in the first list box and based on the selection in the second list box, populate the third. I would like to do this using AJAX. How can I do it? Can someone please give me the code snippet as I am a complete noob when it comes to AJAX and I kinda am running outta time to finish implementing it. Additionally, should I use ASP boxes or HTML <select> tag?

I have a product select page that is really slow to use because 6 dropdowns must be populated and the page reloads after selecting each box, to get the options for the next box.
I want to speed it up as follows:
1) User selects one of 50 products from a dropdown list.
2) Page reloads, and all the possible options for the remaining 5 dropdown boxes are now populated (ie. list options all stored client side)
3) User can freely input the remaining 5 dropdowns without the page reloading.
i am writing a script that will update a dropdown list based on the selection of a previous list. the script is run by a PHP script, so instead of posting the PHP, i will post an example client-side script. the hierachy is: category, sub category, brand (but sometimes there exists no sub category and the PHP script queries and adds brands instead) everything works correctly, except for one major issue: you can not change the selection of the third (brand) box this could be an easy fix for some coders, but i am not experienced in javascript and could really use some help. here is an example script, sorry it is so long

I have been struggling on a bit of code for a while now. I need to populate a second drop down list (Region) based upon the selection of the first (County).I have found a piece of code that works on its own and have adapted to suit my needs - see below. However, when I drop it into my main page the javascript is not working. It's because of the formObject but I just don't know enough to resolve this! Furthermore, I need the textboxes the user has already completed in the form to retain their value once the javascript kicks in as the completed form will submit to a database.This piece of code is working well . . . .
<?php
$link = mysql_connect('myhost', 'myusername', 'mypassword') or die('Could not connect: ' . mysql_error());
mysql_select_db('mydatabase') or die('Could not select database');[code]......
I have quite a few calls on my page at different points to populate dropdowns using jSon responses from the server. It is all working fine now apart from one issue. The name of the field that sets the value and text of the new Option(s) being put into the dropdown.
[Code]...
I am populating a number of Select boxes on the server-side with a large number of options. I'd like to get the response size down without taxing the client browser too much. What do you think is the most efficient way to approach this problem?
Here are some considerations: The option text/values do not change very often, but could potentially change in the future. The page that holds the select boxes should never be cached, there are other aspects of the page that need to remain fresh. Firebug with YSlow is saying that the primed cache size of the page is 300Kb with all the select dropdowns and options, if I remove the options, the primed cache size of the page is 80Kb. I am considering breaking out the text/value pairs for the select boxes into a separate file that is cache-able calling it "valueTextPairs.js" and referencing it with a query string and some sort of server-generated MD5 hash of the data, so that if any of the values change, the client's cached version will be replaced by the latest version. Like so:[URL]...
Provided I do this, I anticipate that the primed cache size of the page will be reduced down to 80Kb (which I like) -- however, before I take the plunge, I am curious what you all think the performance effect will be?
I know the number of bytes on the wire will be reduced, but will this put a lot of additional pressure on the client's browser because I'd need to traverse the name/value pairs and add the options to the select boxes dynamically on the client end? If it seems reasonable to do this, what jQuery approach would be the most efficient? $('#selectId').html(options) with options = one big string? Adding each child option to the select in a loop? Something else?
Some client end folks are using IE6 so I am trying to tax the browser as little as possible, while also reducing the size of each request, trying to find a happy medium..
I've looked around and from what I can tell, the code seems right. Basically crating a JS array and passing PHP values to it to use in an onChange to fill a text field. The dropdown gets populated fine but the text field does not autopopulate onChange. I'm not too fluent with JS but have a good analytical mind and from what I can see, the logic seems right.
<?php
include('connectdb.php');
$CENTRE = $_SESSION['centreAFB'];
$qryFormList = mysql_query("SELECT * FROM tblLogin WHERE ACCT_TYPE = '2' AND loginCENTRE = '$CENTRE' ORDER BY loginNOM");
echo "<script type='text/javascript'> var formCourriel = new Array()";
while($resFormList = mysql_fetch_assoc($qryFormList))

how to populate checkboxes based on the dropdown menu selection
View 2 Replies View RelatedI want to populate a combobox with data pulled from a mysql db . The value of second combobox depends on what's been selected in first combobox. I assume pulling the data completely when loading the combobox and then filtering it locally to populate the second combobox based on the selection in first combobox will suit my needs so that i do not have to query server.What is the best way of doing it?
View 3 Replies View RelatedI am trying to construct a Jukebox for my website. I have spent considerable time all over the WEB and at this forum which addressed the issue in a 50 page thread. Please see: [url]
I got a lot of ideas from this thread but still cannot figure a way to do the following within the Jukebox. These are my main two questions for everything below:
1.How can I have the Jukebox cycle through all tunes and then start over from the beginning?
2.How can I allow the user to select a tune from a list but not a drop down list, have the Jukebox start from the users selection and then play all songs to the end. Then as in #1, start over from the beginning?
Per this thread I came away with basically two ways to assemble the jukebox. One uses links in a drop down list which the user can choose from. The other is to use an .m3u playlist. The user can only select a playlist from the drop down.
Below, I have included the code for each Jukebox. To see the Jukeboxes in action please go to my website where I have posted some test pages exhibiting the jukeboxes that I am referring to.
The following is the Jukebox which utilizes an .m3u playlist. If I end up using this idea I would like the tunes in the .m3u playlist to be displayed and allow the user to be able to choose a tune in the list. Then have the list play to the end of all tunes in the list. Then start over from the beginning of the list. After this code is the .m3u playlist.
Go to url removed and click on the link that says:
Jukebox utilizing an .m3u playlist:
Here is the .m3u playlist for the above code:
The following code is for the Jukebox that has a list of links in a dropdown list. If I go with this idea, I would like for the list not to be a dropdown list but just a list of tunes. The user should be able to click on any tune in the list and the player should start from that point, play all the remaining tunes in the list and then start from the beginning.
Go to url removed and click on the link that says:
Another idea I found on the WEB also uses an .m3u playlist. The good thing about it is that it lists all the tunes in the playlist which the user can then select from. This jukebox calls up an entire Windows Media Player. If I was to use this idea I would like to be able to disable the left side of the player where the user has options such as burning to CD, Media Guide, Radio Tuner etc¦

I am trying to populate data from an xml file when a certain catergory from the dropdown menu is selected. The dropdown menu is also populated from a xml source different from the one where the data is stored that needs to be pulled. so when a category is selected from the dropdown - the selected value will populate the data from the xml source. I am having trouble displaying the data when a category is selected from the drop down menu.

I created two drop downs, where the second one dynamically updates according to first selection. Now I jus have 2 members in first drop down and 20 in second drop down. I hard coded using javascript. But by the end of this year the number increases to 100's, then we cannot hard code it. I use html,javascript,jsp for the webpage. Is there a way to populate the dropdowns with data in a text file where they can update the text file with new members.
View 5 Replies View RelatedI have two drop-down fields that are populated separately from the database. Here is my HTML/PHP code

</select></td></tr>
This code works well as long as the two drop-downs are independent of each other. The result table has VenueName as an element, so each venue has a set of result records in the result table. This is how I want to change it: The Venue dropdown will remain as it is. Once the Venue Name is selected I want the result dropdown to populate with ONLY the result records containing a match on VenueName that was selected in the venue dropdown. How do I do that? Is it with a onChange Event? What are the changes that need to be made? How do I communicate to the second drop-down what was selected in the Venue drop-down??
I have several lists each of several hundred selectable items. I send
all lists to the client along with the javascript. When the user types
the first letter of the item in a text box, I know which list to
present- it is likely the user will wish to view several of the lists
concurrently (I am not concerned at the extra load time of a few
thousand items sent via javascript). However, I am trying to do
everything client side- (even if I use ajax to call the list from the
server, there is delay at the client side as the listbox is populated
with appropriate items) - can anyone think of a manner of presenting a
long list dynamically, based on the first letter typed, client side
and with the absolute minimum of delay? (These items then need to be
selectable)
