Light, lean, & effective: BenchMax is a simple utility for the weightlifting enthusiast to whom the details matter. BenchMax is an application that allows users to calculate an estimated weightlifting one-rep maximum quickly and effectively. It also provides users with a table of commonly-used percentages and their associated values when compared to the calculated maximum, that are commonly used in designing workout programs.
What's New in Version 1.0.1:
-Added support for iPad/iPad Retina Display.
-Added ability to calculate units in kilograms(kg).
-Added ability to freely convert input weight, percentage tables, and max between pounds and kilograms.
Casting strings as integers for sorting
If you're coming on an existing web application project and find yourself building sortable tables, chances are you've come across situations in which you need to sort these tables numerically but they're stored as type VARCHAR (aka strings). If so, don't fret! you don't have to rebuild your table. Simply cast the fields as strings in your SQL query (whether this be in Drupal, C#/ASP.NET, general PHP, etc..) do your own hunting on where to do so. The actual query, however, is:
SELECT * FROM <tablename> ORDER BY CAST(<columnname> AS SIGNED) ASC
to cast the field as an integer and correctly sort the numerical order. Variations of this query will have different effects - chop it up at your convenience!
Evaluating Regular Expressions in PHP
It goes without saying that there are obvious benefits to using server-side validation of forms. From e-mail validation to username formatting, it's important to use regular expressions to make sure any data being passed is both secure and compatible with your SQL database. It's also important to use server-side validation over client-side(ex. JavaScript) to prevent SQL injection or any other malicious behavior.
Below is a basic example of how to evaluate a regular expression using PHP. IF you're somewhat familiar with the language, the code should be easy enough to follow. Please feel free to use at your own discretion; remember once a field/string has been evaluated the options are endless when handling the results!
A live example of the following code can be found here.
NOTE: Please forgive the formatting in the following snippet. This is a current limitation of the blog and the majority of the whitespace is formatted incorrectly.
--------------------------
<?php
#pull POST variable from form submission
$str = $_POST['str'];
#define the function run the regular expression for the string value submitted
function parseString($x){
#define the regular expression and set as variable: will return 1 if true(validated) or null if
#the requirements are not met
$evaluated = eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $x);
#echo the input string for the sake of seeing results
echo $x;
#evaulate the regular expression and return a message if true or false
if ($evaluated){
echo " You've entered a valid e-mail address.";
} else {
echo " Please enter a valid e-mail address.";
}
}
?>
<!DOCTYPE HTML>
<body>
<?php
#execute the parseString function and pass the form-submitted variable
parseString($str);
?>
<br />
<!-- html for the form submitting the field/string under question -->
<form method="POST" action="regex.php">
<input type="text" id="str" name="str" /><br />
<input type="submit" value="submit" id="submit" />
</form>
</body>
</html>
