Dropdown Lists
I've been doing a site for a while now that has several drop down lists in a form. On one form there is the same drop down list repeated 3 times from the same table in a database but with different values. What would be the best way to repeat the code without repeating all of the code. Basically looking at an more economical way to do things. Would you do a while statement and loop through them or maybe a single array and call it when you need it. Any opions?

Dynamic Dropdown Lists
I am recoding a greeting card website.

I am using dropdowns as filters for items in a DB, so when the user picks "animals" from the "theme" dropdown, the returned cards all feature animals, and when the user picks "birthday" from the "message" option, the returned cards all feature birthday cards.

However, there are some combinations that don't return any results, for example "get well" "floral" cards. Code:

Create State-cty Dropdown Lists
I've gotten everything up and running except for this -- I'd like to
be able to have people have a dropdown list of cities in the US to use
(or wherever) and not have to input them manually into a text field.
When you do then there are issues of misspellings, etc.

Now I have a list of cities from each state that is a sample that
works in an html page. Problem is that it takes up 2 MB! Way too much
to load on a single page and I was wondering how this is accomplished
best -- do people use javascripts that can pull information from
another flat flie? Do people use PHP to connect to a mysql database
that might have a list of these fields and then reloads the page?

I'm really not sure of best options and would be grateful for anyone
to give me pointers or whether there are other examples and even
places to buy these databases (not likely but good to have if I decide
to do so.)

Auto Select Dropdown Lists From Db Values
I want a simple HTML drop-down list like this: Code:

<select name="select_1">
<option name="option_1" value="option_1" selected="true">
<option name="option_2" value="option_2" selected="false">
</select>

to be able to automatically select a value according to a value in a table in the database. For example, if a MySQL table has a field named "field_1", and one of the rows has a value of "option_1" in that field, I want the list (using PHP of course) to automatically select the option name "option_1".

Saving Selection In Drop-down Lists In PHP After Page Reload?
I can't find an answer to my quesiton anywhere.

Given a drop-down list with USA states and other text fields I pass
this information for further processing via PHP. If any of the required

fields is empty, the PHP script would return an error and reload the
form page asking to fill out those fields. All entered information is
saved... except for the drop-down list selection. I tried to write a
Javascript function which is echoed by PHP, but interpolation of PHP
variables in the Javascript section gives a syntax error message in
Javascript.

The PHP script returns, e.g., an "AL" string for Alabama. Of course, I
don't want to write PHP code for each option to make it selected.

Refresh Only One Dropdown Box On A Page
I have a form with many fields and a drop down box called fruit. Lets say it has three choices:

apple
orange
banana.

If the choice is not on the drop down box e.g. grapes the user clicks a link to a new table called add_fruit to add the new fruit and details about the fruit. On submit I want to close the add_fruit table and go back to my original form - refresh only the dropdown box "fruit" - so now the user can pick grapes.

Creating Dynamic Page Based On Dropdown Selection?

3 1999 Audi S4

Two PHP Scripts On One Page Not Working?
I have two small PHP scripts running on a test page

Both scripts work perfectly when there is one script on a page. However, if I place two on the page (one above the other), the second script will not render. I get no PHP error messages - the script will just not render.

I think the PHP Scripts are OK as they were automatically generated by RSS Feed Burner and both do run separately.

There may be an issue with having separate calls of some kind on the page or my server might not be set right. I did a server test that I think shows that it is OK but I am not sure. The only think I have in my htaccess file for PHP is: "AddType application/x-httpd-php .htm .html" .

I am new to PHP and was wondering if anyone can see why both scripts will not run together?

Flash Not Working On Page
I have inserted Flash animation on my page as normal (using Dreamweaver)- only it won't display in the browser for this site - which has various php/mysql pages on it - but this one is a simple html page - which displays the html - but not the Flash ?

The flash displays in the browser if I insert it into a page on another site - which does not use php/mysql.

Is it to do with the set up of the site which uses php/mysql ? - e.g. the fact there's testing server settings. My sites/servers are hosted remotely - and not on my own machines.

Working With Dates On The Modify Page
I have a column in a table called testimonialDate. It is of type 'date'. When trying to modify a record, I can get it to display nicely on the modify page using:

$newdate=date("m-d-Y", $testDate2);

I've found a lot of hints on the internet for displaying, but how do I send the info back up?

Maintaining Mailing Lists
I've few doubts; I'm asking two problem here.

1st, can we use PHP for maintaining mailing-lists. Say, we've 1000 users, need be e-mailed a subscription newsletter i.e. $message is same, loop through e-mail array in db.

2nd, Web site search. We maintain database after reading files using PHP and manipulate results from db.

Question is, if PHP is a solution for these problems, also, when users' ( 1 ), keywords' ( 2 ) dbs grow big! There is also a limit of a PHP script execution. In 1st case, PHP has to parse, suppose 10k subscribers, and generate 10k e-mail for sendmail program.

Is PHP feasible for such things. What else, is a better and professionally used solution. I don't know CGI? Perl?

Less-expensive Way To Set Up Defaults In Lists Etc?
I'm currently setting up default selections in <select> lists by
passing an array of those defaults as keys ( 'valuefoo' => true ) as
an argument to the function that sets up the list. Then, as I build
each <option>, I call array_key_exists ( thisoptionvalue,
arrayofdefaults ) to check whether to include the
'selected="selected"' string.

So the code looks something like

Routine ( array( 'valuefoo' => true, 'valuebar' => true ) ) ;
.....

function Routine ( $defaultvals )
{
for ( $i= etc. )
echo '<option....' . ( array_key_exists( 'curroptval',
$defaultvals ) ? 'selected="selected"' : '' ) . etc ' ;
}

(I've elided a lot of syntax, but you get the idea)

That seems slow and tedious. Does anyone know a cheaper way?

Quote's Invoices Lists...
I need someone to bounce some ideas off.

This is what I'm trying to do, I want to be able to create a script that
will spit out a quote based on the information filled in.

The part I'm stuck on is. Entering all the items in.

Ok, say I have a form, it starts off where you put in all the details
(eg, who the quote is for address phone no etc.)

Then there will be a list of items to go onto the quote.

Now this is the part I'm stuck on. I'm thinking maybe something like an
add new item button that opens a new window and then you enter in the
details for each item.
This then adds each item to the quote. Each item that is entered can be
added directly to the database. So what I'm thinking maybe is a popup
window that you fill in the details for each item, you hit submit, and
then it goes back to the origional quote page, but now with the item
added to the list.

Maybe is there java script where you can open a new window and then
refresh the parent window when the child is closed? this would then have
the items listed.

Drop Down Lists And Textfields
I've found this is a great place to learn, so hopefully such can happen with the following:
