AyKay47 Posted November 8, 2011 Share Posted November 8, 2011 in order for your code to work, $_GET['img'] will need to be an array, which I assume it's not if you are having issues with this.

Pikachu2000 Posted November 8, 2011 Share Posted November 8, 2011 Why does it need to be in an array? Is it more than one value? Link to comment https://forums.phpfreaks.com/topic/250705-problems-with-an-array/#findComment-1286259 Share on other sites More sharing options...

Pikachu2000 Posted November 8, 2011 Share Posted November 8, 2011 How do you have the form set up? Can you post that part of it here? Link to comment https://forums.phpfreaks.com/topic/250705-problems-with-an-array/#findComment-1286262 Share on other sites More sharing options...
AyKay47 Posted November 8, 2011 Share Posted November 8, 2011 how do i put it in an array? this will really depend on what method you are using to store the data. As pika said, we will need to see the relevant code, namely the form from which this data is coming from, in order to help you further with this.

richiejones24 Posted November 8, 2011 Author Share Posted November 8, 2011 ye this is the form i am going to use <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <body> <form id="form1" name="form1" method="post" action=""> <p> <label> <input type="text" name="img[]" id="img[]" /> </label> </p> <p> <input type="text" name="img2[]" id="img2[]" /> </p> <p> <input type="text" name="img3[]" id="img3[] " /> <label> <input type="submit" name="Submit" id="Submit" value="Submit" /> </label> </p> </form> </body> </html> Link to comment https://forums.phpfreaks.com/topic/250705-problems-with-an-array/#findComment-1286271 Share on other sites More sharing options...
The Little Guy Posted November 8, 2011 Share Posted November 8, 2011 the name attributes need to have the same values, see below: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <body> <form id="form1" name="form1" method="post" action=""> <p> <label> <input type="text" name="img[]" id="img[]" /> </label> </p> <p> <input type="text" name="img[]" id="img2[]" /> </p> <p> <input type="text" name="img[]" id="img3[] " /> <label> <input type="submit" name="Submit" id="Submit" value="Submit" /> </label> </p> </form> </body> </html> Link to comment https://forums.phpfreaks.com/topic/250705-problems-with-an-array/#findComment-1286275 Share on other sites More sharing options...
AyKay47 Posted November 8, 2011 Share Posted November 8, 2011 seeing your form, I don't quite understand the logic of this. What exactly are you trying to do by storing the data in an array? The way your code is now, this will lead to unexpected results.

richiejones24 Posted November 8, 2011 Author Share Posted November 8, 2011 the array is just one part of a bigger script, how would i fix the form so it works?

Pikachu2000 Posted November 8, 2011 Share Posted November 8, 2011 To make it so the values are sent as part of an array, they need to have the same name attribute, and the square brackets with or without a index name/number. Each set of fields that has the same name attribute will be its own array. <input type="text" name="img[]"><br> <input type="text" name="img[]"><br> <input type="text" name="img[]"><br> <input type="text" name="img[]"><br> <input type="text" name="img[]"><br> Or <input type="text" name="img[one]"><br> <input type="text" name="img[two]"><br> <input type="text" name="img[three]"><br> <input type="text" name="img[four]"><br> <input type="text" name="img[five]"><br> Link to comment https://forums.phpfreaks.com/topic/250705-problems-with-an-array/#findComment-1286291 Share on other sites More sharing options...

AyKay47 Posted November 8, 2011 Share Posted November 8, 2011 your form method is POST, in your PHP code, you will need to change $_GET['img'] to $_POST['img'] Link to comment https://forums.phpfreaks.com/topic/250705-problems-with-an-array/#findComment-1286337 Share on other sites More sharing options...
