Use Select (Newbi Question)

[Zara]

Hello i am new to this forum, but after spendning hours on internet looking for an answer i joined here.

 

What i want to do is basic and maybe i am doing it totaly wrong.

 

 

 

 

 

My commandline looks like this in my php file

 

 

SELECT meta_value FROM `wp_usermeta` WHERE user_id=1 and meta_key='rcp_status'

 

I have a mysql database called blogg and i have a table called wp_usermeta in this table i have allot of rows with data in them.

 

I have been in phpadmin and tryed the commando SELECT meta_value FROM wp_usermeta WHERE user_id=1 and meta_key='rcp_status' and it gives me correct answer "active" is the text but when i do it in php its emty and i get no errors so what could be wrong?

 

My logg.txt file only show results for $sms_kod and $sms_id and the row where $results should be is emty.

 

 

 

 

 

 

 

Hole script:

 

<?php

 

$sms_id = $_POST["userid"];

$sms_kod = $_POST["koden"];

 

 

 

 

$link = mysql_connect("localhost", "$username","$password");

 

mysql_select_db("blogg",$link);

 

 

 

$result = mysql_query("SELECT meta_value FROM wp_usermeta WHERE user_id=1 and meta_key='rcp_status'");

 

 

 

 

 

 

echo mysql_error();

 

//For debugging

 

 

$myFile = "logg.txt";

$fh = fopen($myFile, 'w') or die("can't open file");

fwrite($fh, $sms_kod);

$stringData = "\n";

fwrite($fh, $stringData);

fwrite($fh, $sms_id);

$stringData = "\n";

fwrite($fh, $stringData);

$stringData = "\n";

fwrite($fh, $stringData);

fwrite($fh, $result);

 

 

fclose($fh);

 

 

 

 

?>

After the query you need to fetch the returned data

 

$result = mysql_query("SELECT meta_value FROM wp_usermeta WHERE user_id=1 and meta_key='rcp_status'");

$row = mysql_fetch_assoc($result);
$meta_value = $row['meta_value'];

[sowna]

simply you can use like this,

 

$result = mysql_query("SELECT meta_value FROM wp_usermeta WHERE user_id=1 and meta_key='rcp_status'");
$meta_value = mysql_result($result,0);

[Christian F.]

Do note that mysql_result () should be used only when you're fetching one field, and only one field, from the DB. Otherwise the mysql_fetch_* () functions are recommended, due to efficiency.

 

PS: You should also consider moving on to PDO or MySQLI, as the mysql-library is old, outdated and no longer being developed. All of which means that it'll become deprecated soon, and then removed from PHP. Better get a head start, after all.

Thanks guys! Now it works i went with "

$result = mysql_query("SELECT meta_value FROM wp_usermeta WHERE user_id=1 and meta_key='rcp_status'");

$meta_value = mysql_result($result,0);

"

 

Now i am done with my php file, ofcourse it dosent work and i dont get any errors as well. Is there a good way of debugging php files?

 

When i run it in my webbrowser the page is white. My ide was to inplant echos but that ide dident really work. Is there some kind of editor i can use that will show that i have done right on all the "(" ")" and stuff like that?

 

 

 

Here is my code if anyone se any errors please help me correct them. Or point me to a good editor or similar that would help me find my errors.

 

 

 

CODE:

$datem = date('Y-m-d', strtotime("+1 month"));

$datem1 = "$datem 23:59:59";

 

$link = mysql_connect("localhost", "$username","$password");

 

mysql_select_db("blogg",$link);

 

 

 

//kolla om kodefinns eller ar anvand. check if the code is used or not

 

$result1 = mysql_query("SELECT used FROM wp_sms_nummer WHERE kod='$sms_kod'");

$used_value = mysql_result($result1,0);

 

 

 

 

//not used do this

How to past the code into a code block here?

[Pikachu2000]

You almost had it . . . Use either

 . . . 

or

 . . . 

tags, or you can highlight the code in the editor box and click the <> button above.

I hope i dont spam to much but seems that i cant edit my another post.

 

 

Now i am done with my php file, ofcourse it dosent work and i dont get any errors as well. Is there a good way of debugging php files?

 

When i run it in my webbrowser the page is white i expected it do make the tabels /update tabels and also print my echos on screen nothing happend. My ide was to inplant echos but that ide dident really work. Is there some kind of editor i can use that will show that i have done right on all the "(" ")" and stuff like that?

You need to turn on error reporting. There are several good links in my signature for you.

[Jessica]

Also look in your log file.

[Barand]

Do you have any error reporting turned on.

 

That code does not even parse corrrectly - you have a misplaced ; on line 27 (move it before the } )

also line 52

 

and remove the ; on line 63
