  1. Two Forms, Two Actions, Same Page

    BACKGROUND: Good ideas are sometimes like luck, they come in streaks. Thanks to the experiential wisdom of this forum and those around me in the Galvanize collective workspace, I have decided to tarry a little longer with the reconstruction of my data base. Indeed, I have learned a new term -- normalization. What before I intended to achieve with row duplication I hope now to achieve with simple updates. In order to achieve this important structural change and still retain the benefits of the old structure, I must disengage one of my form's <fieldset>s and create from it a new form that is submitted manually and only occasionally. It would appear that the small changes to the separate table that this fieldset previously replenished with each new form submission can now be achieved with MySQL TRIGGER and UPDATE statements. This strategy has led to the following two questions: QUESTION ONE: Under the assumption that one can have only one $_POST variable per page how does one typically go about using the same $_POST variable for multiple forms on the same page? If I were to implement this task on my own, without the advice of others, I would create a bivariate if-. else if-, else- statement that tests for the present of one of two variables and then handles only that data associated with the form submitted. Is there another, perhaps more thorough, separation that does not include the creation of a separate form page? QUESTION TWO: When executing a MySQL TRIGGER that updates a single row value of a single column of a table different from the one that executes the trigger, will the DEFAULT setting for the UPDATE statement trigger a timestamp with the ON UPDATE CURRENT_TIMESTAMP? As always your wisdom would be well-appreciated. Roddy
  2. OJBECTIVE: My goal is to send a $_GET or $_POST variable from an RSS feed when the user clicks on a link housed within the <description> subelement of an <item> tag. The data from the superglobal will be used to display content on a host webpage designed as an index for all <item>s hosted within the same and ultimately other channels. CODE SAMPLE: <item> . . <description>Grammar Captive Free Weekly Podcasts: <![CDATA[<a href='http://www.grammarcaptive.com/podcasting/podcasts.php?episode_no=003' title='Episode Title' target='_self'>Episode No. 003</a>]]></description> . . </item> QUESTION: Will by placing the link with the intended address and appended http request code into a CDATA tag allow users to send the desire episode number to the designated PHP page for processing. ADVANCED STRATEGY: If the above is possible, do you have any suggestions in regard to the best way for the receiving PHP page to call up the material relevant to the designated episode? For example, I am contemplating the use of a SWITCH statement that would route the incoming episode number to a block of PHP or Javascript code that would insert the contents of another webpage, whose URL is the episode number of the incoming HTTP_REQUEST, and whose content is dedicated to the episode corresponding to the incoming episode number, into another webpage (likely the same page that contains the SWITCH statement) that serves as an index for all completed and upcoming episodes.

  3. This is another strategy question. Multiple answers are welcome. What is written in present tense should be thought of as future, not yet realized activity. BACKGROUND: I have constructed a form whose intended purpose is to create chunks of data including text, links, and images that can be entered into a MySQL database for both immediate and future use. For the moment, I am only concerned about their immediate use. From the database these same chunks of data are retrieved and entered into an HTML template that serves as the backbone for an email insert that is, in fact, a weekly newsletter that can be viewed directly in one's mailbox or viewed on line should the insert fail. The mail insert is then distributed using PHPMailer that takes advantage of an assembled list of subscribers stored in the same database. Based on previous experience I believe that I am well able to handle this routine except for one hitch -- the treatment of the HTML data. MY DILEMMA: In the form are <textarea> elements that I intend to fill with a combination of plain text, HTML, and CSS styling attributes. That the HTML does not render as anything but the code itself is not a cause for concern on my part. Rather, I am bothered about how to send this data to the remote server. Now, I have been taught to filter and sanitize $_POST variable data as it is received and before processing. This time, however, I am sending the data to myself, and what will be generated and sent to my subscribers will also be generated by me. Do I even need to worry how about filtration and sanitation when I am both the source and the receiver of the data? Further, it is my understanding that MySQL is indifferent how the data is received, and that it will automatically return data in the same format that it is received. Am I making a big ado about nothing? By the way, it is not just a matter of filtration and sanitization. Take, for example, the following script used to process form data on the same page that it is entered. <form id="sevengates" method="post" action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']);?>">
  4. BACKGROUND: I am setting up an email verification routine that receives $_POST data from a form and sends a confirmation email to the applicant with a verification link. The form and the PHP processing routines that store the $_POST data in a MySQL database, and that send out the confirmation email in text format are contained in the same document. The HTML formatted confirmation email is contained in an external file and is included using the following PHP-Mailer method: $mail->msgHTML(file_get_contents('../../confirmation_mail.html'), dirname(__FILE__)); GOAL: Include in the external HTML file information obtained from the $_POST variable before the email is sent. WHAT DOES NOT APPEAR TO WORK: I have tried placing statements similar to <?php echo "blah, blah, blah" . $variable_name . "blah, blah, blah"; ?> in the external file in the hope that the value of $variable_name would be read into the file before it is sent. Unfortunately, this does not work. ANY SUGGESTIONS?
  5. Php Posting Values Incorrectly

    hello everyone, it is long time ago that i visited this forum. and as i see there is better user interface. i really enjoy it. now to my issue: ap-town.php for example select options are postcodes: NW2-Cricklewood - value="40"N1-Hixton - value="44"NW2-Kilburn - value="39" <form action="ap-town-process.php" method="post"><select name="town"><option value="" selected="selected">Destination Town</option> <?php while($town_rows=mysql_fetch_array($town_result)) { ?> <option value="<?php echo $town_rows['lhr_town_value']; ?>"><?php echo $town_rows['lhr_town_to'];?></option> <?php } ?> </select><input type="submit" /></form> ap-town-process.php <?php $ap_town_towns=$_POST['town']; $query_towns=mysql_query("SELECT * FROM lhr_town WHERE lhr_town_value='$ap_town_towns'") or die(mysql_error());$fetch_towns=mysql_fetch_array($query_towns); ?> <form action="ap-town-execute.php" method="post"> <input type="text" name="ap_town_dropoff" value="<?php echo $fetch_towns['lhr_town_to'];?>" readonly="readonly" /> <input type="submit" /></form> the drop in ap-town.php takes the values from the database and would be processed at ap-town-process.php. if i select NW2-Cricklewood in the ap-town-process.php it would give me N1-Hixton altough the values are completly different. in some cases the values are the same, but the but the names area names different. please help me fix this issue.
