PHP - Template Handling Ssi

Hello there,
I'm having a problem displaying money correctly with php. I have a field called "balance" with the type float(10,2), in this field I have a number store as "34.55" which I can go in and look at within phpmyadmin but when I echo this value on the front-end of the site it is displayed as "34.549999237061"
Can someone please help?
Regards.

This doesn't work. Based off what I have seen online, it is suppose to.

Basically, this is what I tried, and the quote is what was returned. I have no idea how to get this to work. It should have been pretty standard
based off of the PHP documentation. The Xpath idea I got from someone else. Either way if I try to use find element by id or tag name it still
returns an empty array, no matter what.

Any advice on what I am doing wrong is appreciated. It doesn't matter what URL I try, none of them seem to work.
Code: [Select]
<?php
$school_data = file_get_contents('http://www.infotechnologist.biz');
$doc = new DOMDocument();
$doc->validateOnParse = true;
$doc->loadHTML($school_data);
$xpath = new DOMXPath($doc);
$tags = $xpath->query('div');
echo '<pre>';
print_r($tags);
echo '</pre>';
?>

Hi,

I'm a beginner in PHP OOP and I'm with some doubts about the correct way of handling errors in PHP.

Look at this function for example:


public function deleteFileFromDisk($fileNameToBeDeleted) {

    $handle = unlink($fileNameToBeDeleted);

    if (!$handle) {
        $result = "(this->deleteFileFromDisk) - Error, " . $fileNameToBeDeleted . " not deleted.";
    } else {
        $result = "(this->deleteFileFromDisk) - Success, " . $fileNameToBeDeleted . " deleted.";
    }
    return $result;
}


Is this the correct way of doing it, or I can do better than this?

Let me add some details of what I'm achieving...

I'm running class methods, and I need to control errors in the process. If any call to the object throw an error I need to catch, stop all the process and send an e-mail with the error.

Here are the object interactions:


$testar_classe = new geoIpImportCSV('geolitecity', 'http://geolite.maxmind.com/download/geoip/database/GeoLiteCity_CSV/');
$testar_classe->downloadAndSaveFile('./', $testar_classe->obtainDownloadFileName());
$testar_classe->uncompressZipFile($testar_classe->obtainDownloadFileName(), '.');
$testar_classe->deleteLine(1, 'GeoLiteCity-Location.csv');               
$testar_classe->deleteLine(1, 'GeoLiteCity-Blocks.csv');
$testar_classe->deleteDataFromTable('tabela1');
$testar_classe->deleteDataFromTable('tabela2');
$testar_classe->insertLinesToDb('GeoLiteCity-Location.csv', 'tabela1');
$testar_classe->insertLinesToDb('GeoLiteCity-Blocks.csv', 'tabela2');
$testar_classe->deleteFileFromDisk($testar_classe->obtainDownloadFileName());
$testar_classe->deleteFileFromDisk('GeoLiteCity-Blocks.csv');
$testar_classe->deleteFileFromDisk('GeoLiteCity-Location.csv'); 


Which is the best way of handle this? Create a new method to take care of the exceptions? There are any examples on how to do this?

Best Regards.

I have a prepared statement that returns an Article from my database.  It then binds the results-set to variables.

Most of the fields in the query are "required", so I *assume* that I am guaranteed to always get values back for those fields...

Is that presumptuous?

Here is a snippet of my code...

// Execute query.
mysqli_stmt_execute($stmt);

// Store results.
mysqli_stmt_store_result($stmt);

// Check # of Records Returned.
if (mysqli_stmt_num_rows($stmt)==1){
// Article was Found.
$articleExists = TRUE;

// Bind result-set to variables.
mysqli_stmt_bind_result($stmt, $articleID, $title, $description, $keywords, 
$heading, $subHeading, $publishedOn, $author,
$body, $referenceListing, $endnoteListing);

// Fetch record.
mysqli_stmt_fetch($stmt);

// Close prepared statement.
mysqli_stmt_close($stmt); // ????



Is it sufficient to have code like this...

Code: [Select]
<title><?php echo $title; ?></title>
...or do I need more error-handling??

Hope that makes sense?!

Thanks,


Debbie

Hi,

I have an HTML form created using Dreamweaver and now I need a script to handle the form processing. Basically what I need is for the form data received from the webpage to be organized in an email and then sent to me. I would also like to display a thank you message in the browser so the user knows it was received. I was planning to do this using CGI but a colleague suggested that CGI is old school and nowadays a developer would use PHP for this task. Is PHP the right solution for this project?

The examples I have found so far always include the HTML for the form and the script needed to handle it in one file. In my case, I have an HTML form already in place and need it to work with a script to perform the email function. I know I need to set "Action=" on my webpage to point to the PHP script but what would the code look like if no HTML is needed? I hope this makes sense...

Thanks for your help!

A form needs to get answers of math quiz, returning numbers, up to 2 digits after the point.
In all form examples I noticed the usage of:  Code: [Select]
...<input type="text" name="name" /...
Cant it be a number? floating or integer? why "text" ?

Also, can I limit the form to accept numerical input only or would I need to learn Ajax for that?

Once I have the answer, I need to compare it to the correct answer. The method I have in mind is to multiply the answer and the correct one by 100 and compare the integer part. Is there a pre-made function that can do the same?

I am inserting last names into the database using mysql_real_escape_string(), and outputting the data into a textbox using addslashes().

When I try to display O'Brian "O\" is displayed in the text box.

The name is saved corretly as O'Brian in the database.

I am printing the string like this:

Code: [Select]
echo "<input type='text' value='" . addslashes($customer['lName']) . "' blah blah...";

anybody have any ideas?

Hello,
Am writing a script that involves user input.
Take an example: a user fills in a wrong username or password at the page login.php, my login processor (processor.php) detects it, how is the error "WRONG USERNAME OR PASSWORD" supposed to be transferred back to login.php.
So far I have been using a session variable to transfer the error but am sure there is a better way to do this without displaying the error on processor.php itself.

Thanx in advance

Ok, so I am kind of just looking for some experience on this one. I am building a billing / referral system that works on a hierarchy. Now the hierarchy is simple and straight forward. However, I am trying to figure out the easiest / least error prone way of handling the payments.

I have an IPN with paypal set up and working successfully. Here is how the system works:

User signs up and refers several users. Each user pays $8 a month (paypal subscription). The system pays $1 7 levels deep. So The payment scheme would look like this:
User 8 pays $1 to User 7, 6, 5, 4, 3, 2, and user 1. Then, the site keeps the remaining $1.

I have the Paypal IPN saving the $8 payment transaction to the database. Now I need to divy it up, but I am split on when the best time to do this would be and how. There is a possibility that the user could pay a different amount less than or more than the $8 and they also pay a setup fee which should not be divided. It should only divide the shares when the current account is paid in full.

Another thing to keep in mind, is that the $8 subscription, 7 levels deep, and the setup fee are variable numbers. (The admin may change it at any time.)

I see multiple solutions, but not sure which would be best as all have possibility for errors in handling.

Any advice would be helpful.

Thanks,
Tom

Hi, i am php programmer , i need help from php expert to create php apllication for large database .
I have database table called "profiles" which contains millions(1.5 to 2 million) of profile of the business companies. This table has 10 fields and there is one field named as "bname" which is name of company , i made this column full-text index for full-text search .

Now , i have to use this table for profile searching (using full-text search), profiles within particular cities , profiles within particular categories etc. This table contains millions of records so it will take lots of time for searching and fetching the reocrd(s) from this table.
Can anybody help me that how can i manage this large table to improve the performance and fast searching with php ? Is there any other technique (algorithm) to manage large database (like facebook,twiiter,orkut)?

I am writing an API for clients to use to integrate with an server API I have written and it will be used in a variety of different environments and used by people with varying coding styles (hopefully), I was just wondering how I should handle errors? I was going to throw an exception, but what if people don't use a try / catch ? Should I return false to allow them to handle an error?


   private function _request($uri)
   {
      if ( ini_get('allow_url_fopen') )
      {
         $this->_response = file_get_contents($uri);
         return false;
      }
      if ( function_exists('curl_init') )
      {
         $ch = curl_init($uri);
         curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
         $this->_response = curl_exec($ch);
         curl_close($ch);
         return false;
      }
      throw new Exception('Allow URL fopen disabled and cURL disabled');
   }



Also, any scenarios where the above would fail to return a result (apart from the obvious lol)


Thanks, Andy

 I have an application that loads several xml files, and then outputs some of the data from the file.  The problem is that every once in a while, the service that provides the xml file does maintenance (or has an error in the file), and my application gives a "Fatal error:  Call to a member function children() on a non-object in..."   I would like to handle the error differently, by displaying "unavailable" instead of the error.  I know that this is usually not the appropriate way of handling errors, because there is a reason for a fatal error.   Any ideas on how to appropriately handle this error?

// Node 217 (GGB)
$xml = simplexml_load_file("http://services.my511.org/traffic/API_KEY_REMOVED_FOR_EXAMPLE");
foreach($xml->children() as $traveltime)
{
    $ggb = "$traveltime->currentTravelTime";
    } 

​echo "GGB:" , $ggb , " Minutes";

Not sure why the PHP variables in the code below aren't interpreting the values that they should be receiving from the HTML form.

HTML form
Code: [Select]
<form action="handle_form.php" method="post">

<fieldset><legend>Enter your information in the form below</legend>

<p><b>Name:</b> <input type="text" name="name" size="20" maxlength="40" /></p>
<p><b>Email Address:</b> <input type="text" name="email" size="40" maxlength="60" /></p>
<p><b>Gender:</b> <input type="radio" name="gender" value="M" /> Male <input type="radio" name="gender" value="F" /> Female</p>

<p><b>Age:</b>

<select name="age">
<option value="0-29">Under 30</option>
    <option value="30-60">Between 30 and 60</option>
    <option value="60+">Over 60</option>
</select>
</p>

<p><b>Comments:</b> <textarea name="comments" rows="3" cols="40"></textarea></p>
</fieldset>

<div align="center"><input type="submit" name="submit" value="Sumbit My Information"  /></div>
</form>
PHP handle_form
<?php #Script 2.2 handle_form.php

$name = $_REQUEST['name'];
$email = $_REQUEST['email'];
$comments = $_REQUEST['comments'];

echo "<p>Thank you, <b>$name</b>,
for the following comments:<br />
<tt>$comments</tt></p>
<p> We will reply to you at <i>$email</i>.</p>";

?>

 

I am uncertain of how to go about checking if my variables have values, and if I have to do this at every step in my code?!   

For instance...

In my "Member" table, the fields "id" and "name" are required.  So when I run this query, presumably there are always values there, right?

Code: [Select]
// Build query.
$q = 'SELECT id, first_name
FROM member
WHERE email=? AND pass=?';

1.) Is that a fair assumption?


After the above code, I initialize these two variables...

Code: [Select]
// Initialize variables.
$memberID = $memberFirstName = '';

Next I have...
Code: [Select]
// Bind result-set to variables.
mysqli_stmt_bind_result($stmt, $memberID, $memberFirstName);

2.) Did I need to initialize those two variables if I am assigning them values a few lines down?

3.) Can I assume that "$memberID" and "$memberFirstName" will have values based on the comments above?


Then a few more lines after this, I have...
Code: [Select]
// Set Session variables.
$_SESSION['memberID'] = $memberID;
$_SESSION['memberFirstName'] = $memberFirstName;
$_SESSION['loggedIn'] = TRUE;

4.) Again, do I need to keep checking for values (e.g. using ISSET)??

I suppose *anything* is possible, but you could also make your code so full of error-checking code that it would come to a screeching halt?!

Please enlighten me!!

I could use some advice on how to capture and display my Users' Addresses.

On my website, I display the User's...

- Username
- Photo
- Location

...next to each Comment they post.


Right now, I just have an *optional* field on my "Registration" form and "Update Details" form which ask for "Location".

The problem, of course, is that that data isn't very useful beyond displaying it?!

But at the same time, how do I capture Addresses from around the globe?!

If all of my Users were in America, I would just do...

- City
- State
- Zip

...but what do I do if someone is from Stuttgart, Germany?!

My fear is a multinational Registration Form like this would scare people away...
Quote

(For Registrants in the U.S...)
- City
- State
- Zip

(For Registrants outside the U.S...)
- City
- State/Province/Region
- Postal Code
- Country


And how would I handle the "Country" field?  If I use a dropdown - which is usually recommended - then I'd have to maintain a very long and dynamic list, plus Users would have to scroll down through a list of a few hundred countries which my come across as *obnoxious*?!


(I'm just trying to entice people to create a User Account, so I don't want to make it difficult!!)

What is the best way to approach this?

Thanks,


Debbie
