image upload and random banner issue

PhantomCube

Hello

Well basically what I've got is a random banner script working. I can add images to a folder on my server called bannerx, inside bannerx is what ever banners I want to have rotated. There is also a text document called bannerx.txt which has all the banners that are in the folder, listed like this:

Then outside of the bannerx folder, is a file called bannerx.php this basically randomizes the rotation of each banner, but checks the bannerx.txt file to see which ones to rotate.

Now the only way to get a banner in the sequence is to add it to the bannerx folder and add its url etc to the bannerx.txt file.

I want to change how this works. I want to be able to have users on my site upload a banner to the bannerx folder, and be able to type in a URL to their site or another site, for when someone clicks on their banner.

I only want to make it a very simple image uploader where I can set the dimensions for the image, the max file size, the file types, and I want to have another text box for typing in their URL and a submit button, and then a confirmation page.

I am having a little trouble doing this how ever.

Any help would be appreciated. Thanks.

EDIT: here is the link to the script so far

I would suggest something like this.
First you need your upload form:

<form name="form1" enctype="multipart/form-data" action="your_script.php" method="post">
<p><input type="hidden" name="MAX_FILE_SIZE" value="//your_maximum_filesize">
Select the file:<br>
<input name="new_image" type="file"></p>
<p><input name="submit" type="submit" value="Upload your file"></p>
</form>

Then in your_script.php you will need to check if(is_uploaded_file).

After this you should rename() your file to match your system(00001.gif,00002.gif,etc.).

If the file is uploaded then you can show a new form for the link:

$the_image = $_FILES['new_image']['name'];
$form = <<<__FORM__
<form name="form1" method="post" action="your_script.php">
  <input type="text" name="the_url">
  <input type="hidden" name="the_image" value="$the_image">
  <input type="submit" name="Submit" value="Type your URL">
</form>
__FORM__;
echo $form;

And finally some code like this one:

$the_image = $_POST['the_image'];
$the_url = $_POST['the_url'];
$data = "<a href=\"$the_url\" target=\"_blank\"><img src=\"bannerx/$the_image\" border=\"0\" alt=\"Free Traffic To Your Site!\"></a>";
$fp = fopen("bannerx.txt","a");
if(fputs($fp,$data)) {
echo "Done!!!"; }
else echo "Error!!!";

I wrote a random image script using a database.

I had 3 columns:

ID, Source and Type

I did a sql query to get the images of the right type, then put the ID's into an array, selected a random item in the array and then outputted the source as the image.

ok well i have most of it sorted. ive only run into one problem when it writes the form to the text file it doesnt write to a new line. if someone can help this would be good. here is the code for the test page

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>
<?php
//form is not (!) submitted
if (!$_POST['Submit'])
{
?>
<form name="form1" method="post" action="<? $PHP_SELF; ?>">
  <p align="center">
  URL:
    <input name="url" type="text" id="url" size="80">
</p>
  <p align="center">
  Image:
    <input name="img" type="text" id="img" size="80">
</p>
  <p align="center">
  Alt text:
    <textarea name="alt" cols="80" rows="5" id="alt"></textarea>
</p>
  <p align="center">
    <input type="submit" name="Submit" value="Submit">
</p>
</form>
<?php
}
else
//our form is submitted
{
//make $fp open the file we write to with Write permissions
$fp = fopen('bannerx/bannerx.txt','a');
$str = '<a target=_blank href="'. $_POST['url'] .'"><img src="'. $_POST['img'] .'" border="0" alt="'. $_POST['alt'] .'"></a>';
fwrite($fp, $str);
fclose($fp);
}
?>
</body>
</html>

basically it lets someone put in a url and alt tag and the url to their banner. problem is the way the random script is, it needs each banners details on a seperate line. So when one person enters their banners details it needs to be on one line, then the next persons will go on the next. and so on and so on.

for to see the form so far

and where it is displayed is

thanks alot people.

OHHHH and i need for the script to check the url the person provideds as their banner (not the url that will be linked to the banner) but the url to the image, i need it to check if the image is a certain size that i can set within the code.

thanks

Ok. to check the image size use getimagesize()

For the new line add \n, this way:

$str = '\n<a target=_blank href="'. $_POST['url'] .'"><img src="'. $_POST['img'] .'" border="0" alt="'. $_POST['alt'] .'"></a>';

ok well i got it to go onto a new line but i did it like this:

$str = '<a target=blank href="'. $POST['url'] .'"><img src="'. $POST['img'] .'" border="0" alt="'. $POST['alt'] .'"></a>' . "\r\n";

just \n wudnt work

anyway the next thing i need to do is get it to check image size.
