PHP - Serve Dynamic Content Based Only On Url Requested

Hi there guys I have a problem that I can't seem to get fixed.   Below Is the code I am using and the Link to the Tutorial:   http://fearlessflyer...x-and-timthumb/                         

Is this possible?
I have a PHP file that serves a file (which is below the web root). That works fine and the download dialog is presented when directly accessed.
Im building and API however, and that file needs to be served via HTTP Request.

Im trying to get it working with cURL but right now its just outputting the raw byte data to the screen.  Anyone had success or know what I need to try to be able to call that PHP file with cURL and have the browser try to download the file?


(i've tried a lot of combinations of settings for this)
Code: [Select]
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_URL,$remote);
curl_setopt($ch,CURLOPT_BINARYTRANSFER,1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $nvp);
return curl_exec($ch);

// side note
I'm hoping the cURL settings don't matter too too much because a C# program will need to request the download.

Hello.

I don't know if this is the right place to ask about this issue, if is not then, please apologize.

I have a small WISP in my town and I would like to offer free internet service at coffee shops, restaurant, and other public places but, this free service will have its limitations: All pages would have an advertisement or promotion on top just like NetZero used to do in the past. I think this is done with frameset but, don't know how to force this for all the pages.

I would like to do this with php/mysql and if the user tries to remove the frame then maybe redirect them to pay per hour/day etc...

I have a linux gateway that runs squid and would like certain ip addresses (free ones) to view pages with this promo on top or even have pop ups from time to time whichever is easier.

Can you please provide any suggestions?

Thanks in advanced for your help.

Hi,

I am hoping someone can help me out with a slight issue I have with php and mySQL.

I have an ajax-powered form with a select (dropdown) field populated through a php function. Based on the user-selected values in this field, data is displayed on the webpage; i.e. selected value 1 returns values x and y on the page. I am now trying to call additional data (value z) from a different table in the same database, and as before, use the selected values from the dropdown to display the data.

For some reason, value z is not changing according to the user-selected value.

This is my code:

[The function to populate the select field]

Code: [Select]
function kfl_get_funds_names()
{
$result = array();
$result['CDF'] = 'Crosby Dragon Fund';
$result['CPF'] = 'Crosby Phoenix Fund';
$result['AMZPIF'] = 'AMZ Plus Income Fund';
$result['KASBIIF'] = 'KASB Islamic Income Opportunity';
$result['KASBCPGF'] = 'KASB Capital Protected Gold Fund';
$result['KASBLF'] = 'KASB Income Opportunity Fund';
$result['KASBCF'] = 'KASB Cash Fund';
$result['KASBBF'] = 'KASB Asset Allocation Fund';
$result['KASBSMF'] = 'KASB Stock Market Fund';

return $result;
}
[the code calling and using the function to interact with the database]

Code: [Select]
$funds_to_display = kfl_get_funds_names();
$current_symbol = key( $funds_to_display );
$current_nav_rates = kfl_get_latest_rates( $current_symbol );
[the code calling additional data, value z, from the database, and using the info in the select field to filter it]
Code: [Select]
$cutoff = kfl_cutoff( $current_symbol );
The display of each of these items is as follows:

Code: [Select]
<?php echo $current_nav_rates['nav_date']; ?>
<?php echo $funds_to_display[$current_symbol]; ?>
<?php echo $cutoff['cutoff']; ?>
I can't get the $cutoff code to display the correct values. It picks up the first symbol to display and doesn't change with user selection. The code for the selection box, by the way:

Code: [Select]
<select id="dailynav-funds" autocomplete="off" name="dnf">
<?php
foreach ($funds_to_display as $fund_symbol => $fund_name)
{
echo '<option';
if( $fund_symbol == $current_symbol ) {
echo ' selected="selected"';
}
echo ' value="' . $fund_symbol . '">';
echo $fund_name;
echo '</option>';
}
?>
</select>
I've tried to get data using $_GET['dnf'] into the cutoff code, but that throws up parse errors. What am I doing wrong, and how can I resolve this issue?

Thanks in advance!

Hello,, I have looked for numerous examples, and have only got part of the answer.
I have successfully populated a drop down list by reading the database.
It populates with a list of quest titles. Once the user selects the quest.
I want a textbox to populate with the Quest Description.

I found an example that uses AJAX/PHP to do this, but it doesn't access a db to read/populate.
The main code is in index.html
The original example you select a country, and it populates a text field with the currency code.
It passes a variable called $country to another file called find_ccode.php.
I changed the first case in find_ccode.php to access my database, and populate the text box with quest description.
Ideally I will like to make this case dynamic based off QuestID, would populate textbox with corresponding Quest Description (QDescrip).
I then tried the other way in index.php
I dynamically populated the dropdown list, and gave the option values the QuestIDs to be passed to $country, but something isn't working.
I have a write files command to let me know what the $country variable is passing, and it never writes. It works in index.html though.
I apologize in advance for my amateurish coding. I still have a lot to learn. I have included the code below, but if you know a more elegant way of doing it. I am creating a role-playing game, as you probably have figured out by now. I hope to one day put it on the web, but right now using it as a way of learning html, and PHP.

I really want to know how to catch the value of the dropdown box. I would like to know what it is before sending over.
also what is this.value. I assume this is what the value of the dropdown box is when you have selected something.

I have been beating my head for days trying to figure this out. Any help is very much appreciated!
