 | Re: PHP Tripod I've never heard of Tripod, but there is a Daniweb member who recently installed a package that puts Apache, MySQL, PHP, and other stuff in a single install. I can't seem to find that post or remember the product name, but it was not "Tripod". I assume you are talking …  |
| | Yes, mod_rewrite is what you want if you are using Apache. If anybody has any proof, I'd like to see it, but the official word from Google and others is that data-driven content (.ASP, .PHP, .JSP, etc.) is not a problem for their spiders. The only problem for spiders associated … |
| | class_session.php is a session management and password protection class. It can be used to perform 2 major functions: 1. Create and maintain session state between page hits. The class does this using simple session cache files into which the session is stored as a serialized array. This is similar to … |
| | This may be a stupid question, but, you do know that with PHP as an Apache module, you need to restart Apache (httpd) to see your php.ini changes? |
| | Debugging tip: You mention that you run the statement in MySql window, and it works, but did you actually copy & paste the statement as generated by your code? Right after you build the $sql variable, output it like so: [php] echo $sql; exit(); [/php] Then copy & paste that … |
| | Yep, the documentation at [url]www.php.net[/url] makes it pretty clear. If you code PHP, you probably want to keep php.net open in a browser at all times! Very nice documentation, and the comments can be a lifesaver---when they are accurate anyway! In my applications, and I have to think in most … |
| | To remove code tags, check out PHP's strip_tags function. [url]http://us3.php.net/manual/en/function.strip-tags.php[/url] You can easily parse or split text based on Returns ("\n"), but you are right, if the user does not hit Return, the text will wrap to another line in the textarea, but is actually not a seperate line. All … |
| | Does your organization use Microsoft Exchange? Do you have a need to incorporate your Exchange data with your PHP web applications? You can use the WebDAV methods to query your Microsoft Exchange Server using the PHP scripting language. Once you wrap your brain around these techniques, the sky is the … |
| | [url="http://somedomain.com/index.php?page=download"]http://somedomain.com/index.php?page=download[/url] index.php: [PHP] <?php if (!isset($_GET['page']) { $page = "about"; // Default page } else { $page = $_GET['page']; } include ("/content/".$page.".php"); ?> [/PHP] |
| | I am not an expert in this field, but the way many barcode scanners work is simply as a keyboard interrupt. That is, they decode the code, and enter the code text AS IF it was typed using the keyboard. So for example, you could have a PHP web page, … |
 | Re: MyISAM vs InnoDB I'm very interested in this answer, too. Hopefully some light will be shed on this thread. |
 | Re: Apache [QUOTE=Bill_Thompson]Edit and debug PHP without having to upload to a sever constantly.[/QUOTE] Quick tip: I use PSPad as my code editor. Like many advanced editors, it includes the ability to edit files directly on your webserver using ftp. So you "open" files from your ftp server. When you save, it … |
| | [QUOTE=bytesurfer]Just wanna ask what is the different with uncommented and commented.[/QUOTE] The difference between an uncommented and commented line is that one is commented and the other is not! :eek: A "commented" line will be ignored by the processor -- comments only exist for the human reader. In many configuration … |
| | [QUOTE=relawson]You know, this feature isn't in Oracle as I recently discovered. Is it considered bad to use autoincrementing numbers? Certainly makes it easy to maintain a primary key with little effort. I am just trying to understand in what situation you wouldn't want to use that feature. Obviously Oracle doesn't … |
| | This is a PHP script that allows javascript clients to request content they otherwise would not be able to. With the popularity of AJAX (using the XmlHttpRequest object in the browser), many developers are becoming aware of the cross-domain scripting limitation. This is a security feature that prevents client-side scripts … |
| | It might be useful for a newbie to understand that it is very easy to enable the IIS webserver on your own Windows computer. The problems are: [list] [*]Speed. Home internet connections do not usually have enough bandwidth to handle much traffic, but this is not a problem for most … |
| | Whether you are using PHP4 or 5, I have 2 PHP classes that will give you almost everything you need. They come with LOTS of code comments and clear examples. [b]class_http.php [/b]- Use this to pull the documents from the remote servers. Includes a caching feature to make you a … |
 | Re: Java or PHP? I'm a "professional web developer". For over 10 years, I've developed browser-based, database applications. I started my programming career writing client-server apps with PL/B. I moved to CGI web apps using PL/B. Then I moved to ASP/VBScript and SQL Server for web dev. When ASP.NET came on the scene, I … |
 | Thanks, Christian. I appreciate your review. My web servers are still FC2. I only use Linux for serving, so I don't install any of the GUI tools. Each new release, though, gets me closer to attempting a complete switch over to Linux for all my OS needs. There are still …  |
| | class_http.php is a "screen-scraping" utility that makes it easy to scrape content and cache scraped content for any number of seconds desired before hitting the live source again. Caching makes you a good neighbor! The class has 2 static methods that make it easy to extract individual tables of data … |
| | class_db.php is a database class that provides methods to work with mysql, postgres, and mssql databases. Other database types can be easily added. The class provides a common interface to the various database types. A powerful feature of the class is the ability to cache datasets to disk using a … |
| | I'm sure the code is good, but I recommend the use of the popular ADOdb class library for database access. It is fast and robust and allows you to use the same code to connect to multiple databases as needed. http://adodb.sourceforge.net/ |
| | Useful, clean, and simple. I like it. |
| | Well, there is a lot to cover here, and a lot you need to learn obviously. :) I will start, and I'm sure others will pitch in as well. Some things you need to clarify: [list=1] [*]Do you have access to and know how to use phpMyAdmin to administrate your … |
| | I just struggled for 2 days to solve this same problem for my company--except I'm using PHP. Your job should be a bit easier since all the official examples are in VBScript, VB, VB.NET, C#, or C++. I would direct you to the Microsoft WebDAV Reference wth code examples. Click … |
| | Hey, I want to write a Word Processor to compete with Microsoft and put Microsoft Office out of business. Can somebody show me how to do that? ;) JUST KIDDING! |
| | So you want a process that will parse these emails to get specific bits of data, store this data in a database, then have an interface to display the data in a meaningful format? If what I describe above is what you want, then you'd go about it by creating …  |
| | I can't help but ask. cynch, you do realize that this login script has zero security value, right? The username and password are written out to the browser and viewable in the source code. |
| | [url="http://www.tgreer.com/class_http_php.html"][b][url="http://www.tgreer.com/class_http_php.html"]http://www.tgreer.com/class_http_php.html[/url][/b][/url] I've written what I think is a high-quality PHP class for screen-scraping external (or internal) web content. The class includes features to cache scraped content for any number of seconds. So for example, if you want to show stock market data on your site that you scrape from a … |
| | Yes, you can script a solution. The question then is, what programming languages are you comfortable with? If you are not a programmer, then you need to find one. You can use ODBC drivers to connect directly to an Excel file. You can then iterate the rows just like a … |
| | That is not an error message, that is simply PHP code being dumped as output. That is what you'll get when you request a PHP-coded file from a webserver that is not configured to process PHP or a PHP-coded file using an extension that the webserver does not expect to … |
| | I've dealt with this scenario extensively, so I think I understand what you are trying to do and what you are asking. As you've discovered, you cannot use client-side script to work with the document object model of remote site content. (Even if that "remote" site is on your own … |
| | You've discovered the truth. This stuff is not easy. It is not user-friendly. When Microsoft asks "Where do you want to go today?", they already know the answer: HELL. Seriously, though, this stuff is not easy. You'll hear people talking about how great and simple MySql and/or PHP is, but … |
| | Building a stateful web application is possible, but not feasible for most application scenarios. As for why a person may want such a thing? LOTS of reasons. An obvious example is a browser-based chat application. You want all members of the chat to see all messages entered as close to …  |
| | I'm sure there are some more commercial products with wizard-type interfaces to help you, but I don't know what they are. I do know that if you are geeky enough, you could build a script that incorporates Wget to find this out. Wget is a non-interactive command-line utility that can …  |
| | Re: url help This is not the correct forum, but I don't see what the correct forum would be. Your issue would be a webserver-specific question--not a programming issue. HOWEVER, you could use PHP to redirect based on the URL...but I don't think that's what you are wanting. What you want is normally …  |
| | [b]ATTENTION ALL NEWBIES![/b] [b]"supplied argument is not a valid MySQL resource"[/b] is almost always the result of an invalid SQL statement being passed to the database. When you are using a scripting language to dynamically build a SQL statement, it is VERY easy to introduce problems into your SQL string. … |
 | What a stupid idea, dj bill! JUST KIDDING :) I think Stewart's point was, if you want something that works like a blog, why not just use a blog system? The open-source Wordpress is free, very easy to use, and supports multiple users. Now, I too have considered creating a … |
| | The values in the dropdown are actual table names in your database? And you want the user to enter a search term, pick a database table, click submit, then see results from that table? What database are you using? MySQL? Postgres? MSSQL? Oracle? This is a simple thing to do … |
| | Dani, My customer's MySql db's are tiny--nothing like your 1GB monster. ;) I simply use the [url="http://dev.mysql.com/doc/refman/4.1/en/mysqldump.html"]mysqldump [/url]command. As you most surely know, this command simply creates a text file that includes all the SQL statements to create your tables and indexes and insert all the data. For you, these …  |
| | Glad to help the csgal. Campkev is correct. Here is how I do it. [PHP] <html> <head> <title>My Web Page</title> <script type="text/javascript"> function LoadTrigger() { alert('This will fire after the page has finished loading.'); } window.onload = LoadTrigger; </script> </head> <body> <p> My Web Page is great! </p> </body> </html> … |
| | If you don't want to use PHP, perhaps you should not post this question in the [b]PHP[/b] forum? Try the Javascript forum. |

 | Let's define "web development". A "web application" can mean a lot of things. My loose definition is any web page that DOES something. If the page content is altered based on user input, that's a web application. Understand there is client-side and server-side coding. Which end of the transaction you …  |
| | [QUOTE=bucwyld]How can a band create a mailing list to send out show responses[/QUOTE] I'm actually not an expert on maillists, but there are specialized apps designed just for this purpose.

[/QUOTE] It's a pet-peeve of mine, so I could not resist responding. :) [b]Java[/b] and [b]Javascript[/b] are not the same thing. They are not even related. They were completely different development paths from 2 completely different companies. The … |
| | Dear csgal, I only recently became a member of your website. My good friend, tgreer, referred me, although now I'm not sure I should thank him. This is not easy for me to admit, but I have a problem: I've become addicted to answering posts in the forum. At first, …  |
| | I think my experience in researching CMS's is the same. I review the features, play with a demo, look at example sites using the system, and conclude that I don't like it. The problem is one I understand well, though. As a programmer myself, I understand how truly difficult it … |
| | tgreer is right. I agree with tgreer that the user should always be allowed to have control over the print attributes. However, I do wish there was a way that the web developer could indicate printing defaults for a document that then the user could override if they wanted. There … |
The End.
