Re: [PHP-DB] pulling images from a database
If you want to be efficient, store only the image metadata in the database (path, filename, creator, date, dimentions, format, etc) in the database. Keep the actual data as a file. -- Regards, Gary SuperID Huntress === FreeSQL.org offering free database hosting to developers Visit http://www.freesql.org Trent Reimer [EMAIL PROTECTED] wrote in message 9ebsd5$q0m$[EMAIL PROTECTED]">news:9ebsd5$q0m$[EMAIL PROTECTED]... I'm trying to find an efficient way to pull images from a database. What I'm saying is that the actual image file itself is being stored as a Binary Large OBject in the database (MySQL) and that I want to use it on a web document. The only way I've been able to do it so far is to call an external script such as: img src=grab_image.php?image=picture1.jpg where grab_image.php goes and connects to the database and spits out the header information and then the binary data for the applicable picture. Is there a more efficient way to do this? Is there any way to embed the image information directly in the document without having to call an external script for each image? -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED] -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

I like to select data out of a drop down box in my form field from a mysql
database. While I do that I also like that it reloads the page and put the
relevant products of that drop down box in another field.
Ex:
Category 1
Category 2
Category 3
are in the drop down box
and when I choose
Category 1
I like to display another field which displays me all the products which
are
in that categorie. I know it can be down just not to sure how?

Re: [PHP-DB] Yet more strings
When I have exact string matches fail where I don't expect them, and using a
LIKE fixes it, the very first thing I check for is embedded whitespace in
the data. "foo " and "foo" and " foo " are not the same.
If this is the case then IMHO the best solution is to fix the data in the
database, but barring that you can probably use the TRIM() function in your
where clause. (note: the MySQL docs show using trim in the output, not in
the where clause so I won't swear that its possible, but it should be)

Gary

CC's suggestion of using mysql_num_rows helped to clarify the problem
rather
than find a solution! The problem is with mysql not PHP. When I use:
$resultp = mysql_query("select Primaryid from primarycodes where Code =
'".$row[Primaryexpertise]."'") or die (mysql_error());
it doesn't return a resource id#, ie the query fails. mysql_num_rows
returns
0.
Using:
$resultp = mysql_query("select Primaryid from primarycodes where Code LIKE
'%$row[Primaryexpertise]%'") or die (mysql_error());
it works, mysql_num_rows returns 1.
I have also checked the string length of $row[Primaryexpertise] (the value
of which is Biology for example) and it shows that there are no "hidden"
characters in the field value (ie strlen returns 7).
Running all this at the mysql shell (is that the word?) results in the
same
errors.
The row values are Primaryid (8) and Code (Biology).
mysqlselect Primaryid,Code from primarycodes where Code like '%Biology%';
\\returns the correct values
mysqlselect Primaryid,Code from primarycodes where Primaryid = 8;
\\returns
the correct values
mysqlselect Primaryid,Code from primarycodes where Code = 'Biology';
\\returns Empty set
I'm no expert (obviously) but something seems odd here.

[PHP-DB] Free MySQL Database Hosting (beta! beta! beta!)
Hi, I'm testing out the concept of offering free MySQL database hosting. Feel free to create a database at http://superid.dyndns.org:8080/freesql/index.php There's no catch, or hidden agenda. I thought it might be fun to try and offer this as a service to people who might be learning MySQL (and hopefully eventually PostgreSQL too) but arent interested in administering a db server.

[PHP-DB] problems configuring php and postgres - call to undefined function
I am trying to get postgresql (pg) support for php working on my RH7 box. I had a working binary installation of postgres 7.03. I thought I had read that php4 had default support for pg, but my call to pg_connect() gave me a "Call to undefined function" error. So, next I tried to re ./configure and add --with-pgsql=/usr/local/pgsql. That would not compile, bombing when it looked for "postgres.h". I did not have the pg source (since this was a binary installation) so I installed that next (in /usr/src, if that matters) I deleted my existing binary installation of pg, and ran ./configure; gmake; gmake install with no errors, and I added an entry in /etc/ld.so.conf as stated in the pg INSTALL. Pg is running fine with several db and I can remotely connect, so I think thats ok. After finishing with the source installation of pg, I re- ./configure php, make and get the same error looking for "postgres.h" kludge I then manually edited the ./configure file and added the include path to /usr/src/postgres/install/kludge After this, I could successfully make php, then make install. I restarted apache, but I am still getting "Call to undefined function". Any thoughts? I'm pretty much out of ideas right now.
