[PHP] problem with storing & displaying image in db
Hello everybody,
I am facing a strange problem while uploading and displaying images in a
database table.
I have taken blob field to store the images.
Images which are less then around 100kb are stored & displayed properly but
images which are greater than 100kb are giving problems while displaying
although no errors were generated while inserting them in database.
what could be the problem ? is it due to the blob type ?
i am using the following statements to insert the file to database.
insert.php
***
$imgsize=GetImageSize($photofile);
$photo=addslashes(fread(fopen($photofile, "r"), filesize($photofile)));
$query="insert into photo(photoformat,photo,photowidth,photoheight) values
('$photoformat','$photo',$imgsize[0],$imgsize[1])";
$photoformat, $photofile are the input fields of the form which is
submitted.
***
in my html pages i use the following :
and my display.php is as follows:
display.php
***
$query="select * from photo where id='$id'";
$result=mysql_query($query);
$photo_rec=mysql_fetch_array($result);
Header( "Content-type: image/$photo_rec[photoformat]; name=".microtime());
echo $photo_rec["photo"];
***
Thanks in advance

Re: [PHP] checkbox validation
Hi jacky,
put an empty square bracket after the variable name as follows:
assuming that your above statement is in a loop we will have following
structure:
*
etc...
now when you submit the form, an array named id[ ] will be posted .
this array will contain the number of elements/checkbox which were checked
on.
so out of 25 checkboxes if you select only 5 checkboxes, then the size of
the array id[ ] will be only 5.
so with another loop you can retrieve all the values as follows:
***
$i=0;
while($i

Hi all
I have a form with the checkbox like this
$query="select id from foo";
$result=($query,$con);

After I submit to next page, at next page, how do I check which check box is
checked?

if ($id=="on") {
do something
}else{

}
I did try this but did not work, what am i suppose to do to achieve this?
