First of all, I’m not PHP geek. But, PHP is my second expert language after CF. I’ve created some freelance projects with PHP . You can hire me if you have some freelance projects for low cost and full reliable.
When I surf website for cropping image, I found this site. It’s cool. Check it out.
One of my friends gave a chance to me to do outsource PHP project for one training center. Her client want to advertise their trainings, their products and their news through internet. It’s simple project but their main point is use can know on the fly the total price of computer once he/she choose each device. It’s create by ajax.

I’ve found one website shows Upload jQuery, flash & PHP.
Our GM assign me to do multiple file upload program. At that time, I was supposed to implement with Ajax. But, one of my friends told me that Ajax cannot handle completely if clients upload serveral files. That’s why I have an idea to implement this program with iFrame.
Index.php
<iframe src=”upload.php” style=”width:260px;height:100px;” frameborder=”0″></iframe><br />
<iframe src=”upload.php” style=”width:260px;height:25px;” frameborder=”0″></iframe><br />
<iframe src=”upload.php” style=”width:260px;height:25px;” frameborder=”0″></iframe><br />
Upload.php
<script type=”text/javascript”>
function startUpload(){
if (document.getElementById(‘message’) != undefined) {
document.getElementById(‘message’).style.display = ‘none’;
}
document.getElementById(‘process’).style.display = ‘block’;
document.getElementById(‘uploadfile’).style.visibility = ‘hidden’;
return true;
}
</script><form method=”post” name=”uploadform” enctype=”multipart/form-data”>
<div style=”text-align:center;”>
<?php
if ($_FILES){
if ($_FILES['file']['error'] > 0) {
echo “<p id=’message’ style=’display:block;’>Fout code: “.$_FILES['file']['error'].”
(<a href=’http://php.net/manual/nl/features.file-upload.errors.php’ target=’_blank’>php-error</a>)</p>”;
}
move_uploaded_file($_FILES['file']['tmp_name'],
“upload/” . $_FILES['file']['name']);
echo “<p id=’message’ style=’display:block;’>Upload!</p>”;
}
}
?>
<p id=”process” style=”display:none;”>
Uploaden…<br/>
<img src=”loader.gif” alt=”loading” />
</p>
<input type=”file” name=”file” id=”uploadfile” onchange=”startUpload();document.uploadform.submit();” />
</div>
</form>
It’s simple, isn’t it?
In these days jQuery and Ajax are so popular in web development. One of my clients told me that, they want to upload multiple files without clicking button. That’s why I have had an idea to integrate jQuery, Ajax and PHP.
Create Upload Button like
<div id="upload_button">Upload</div>
Write following simple coding in your upload form
// You must create it only after the DOM is ready for manipulations // Use $(document).ready for jquery // document.observe("dom:loaded" for prototype new AjaxUpload('upload_button_id', {action: 'upload.php'});
Configure at Ajax Upload
new AjaxUpload('#upload_button_id', { // Location of the server-side upload script action: 'upload.php', // File upload name name: 'userfile', // Additional data to send data: { example_key1 : 'example_value', example_key2 : 'example_value2' }, // Submit file after selection autoSubmit: true, // The type of data that you're expecting back from the server. // Html (text) and xml are detected automatically. // Only useful when you are using json data as a response. // Set to "json" in that case. responseType: false, // Fired after the file is selected // Useful when autoSubmit is disabled // You can return false to cancel upload // @param file basename of uploaded file // @param extension of that file onChange: function(file, extension){}, // Fired before the file is uploaded // You can return false to cancel upload // @param file basename of uploaded file // @param extension of that file onSubmit: function(file, extension) {}, // Fired when file upload is completed // WARNING! DO NOT USE "FALSE" STRING AS A RESPONSE! // @param file basename of uploaded file // @param response server response onComplete: function(file, response) {} });
Add following coding in your upload form
//You can use these methods, to configure AJAX Upload later.
var upload = new AjaxUpload(‘#div_id’,{action: ‘upload.php’});
//For example when user selects something, set some data
upload.setData({‘example_key’: ‘value’});//Or you can use these methods directly inside event function
new AjaxUpload(‘div_id’, {
action: ‘upload.php’,
onSubmit: function() {
// allow only 1 upload
this.disable();
}
});
});
Here is server-side script, upload.php
move_uploaded_file($_FILES["file"]["tmp_name"],
“upload/” . $_FILES["file"]["name"]);

In these days, one of my clients complaint me that he received a lot of spams from reservation form which I created without preventing spams. That’s why I need to put image captcha on it with PHP. For this, I don’t want to use complicated coding, and want to use simple way. That’s why I got suitable solutions from this website.
http://www.phpjabbers.com/captcha-image-verification-php19.html
<?php
session_start();
$text = rand(10000,99999);
$_SESSION["vercode"] = $text;
$height = 25;
$width = 65;$image_p = imagecreate($width, $height);
$black = imagecolorallocate($image_p, 0, 0, 0);
$white = imagecolorallocate($image_p, 255, 255, 255);
$font_size = 14;imagestring($image_p, $font_size, 5, 5, $text, $white);
imagejpeg($image_p, null, 80);
?>
Save this code in a file called captcha.php. Next we need to create our web form like register.html or reservation.html.
<form action=”submit.php” method=”post”>
Comment: <textarea name=”coment”></textarea><br>
Enter Code <img src=”captcha.php”><input type=”text” name=”vercode” /><br>
<input type=”submit” name=”Submit” value=”Submit” />
</form>
All we have to do now is to make the submit.php script which will check if the verification code you enter matches the one that has been randomly generated.
<?php
session_start();
if ($_POST["vercode"] != $_SESSION["vercode"] OR $_SESSION["vercode"]==”) {
echo ‘<strong>Incorrect verification code.</strong><br>’;
} else {
// add form data processing code here
echo ‘<strong>Verification successful.</strong><br>’;
};
?>

Above posts, I’ve described the figure of SQL ASCII Injections and the solutions of this prevented by asp, asp.net and cfmx. In this post, I’ll show how to prevent SQL ASCII Injection attacks by the way of inserting ASCII codes in PHP.
function clean_header($string)
{
$string = trim($string);// From RFC 822: “The field-body may be composed of any ASCII
// characters, except CR or LF.”
if (strpos($string, “\n“) !== false) {
$string = substr($string, 0, strpos($string, “\n“));
}
if (strpos($string, “\r“) !== false) {
$string = substr($string, 0, strpos($string, “\r“));
}return $string;
}
This is just a class, and you always need to call this class before saving data into database from input box. It’s simple though.
