PHP MySQL code

pnh73 · 09-22-2003, 03:24 PM

I am writing code using PHP and making use of PEAR. When i run my script (i am using scripts from a book) i get the following error:

Quote:

Fatal error: Call to undefined function: query() in /home/linHost/www/dev/_lib/_classes/class.news.php on line 233

Does anybody have any idea why this might be?

TIA

Looks like you're calling a function that doesn't exist. Could you post the piece of code around line 233, especially the call to function query()?

Ok here is line 233:

Code:

        if (DB::isError($rsTmp = $this->_oConn->query($sql))) {

            catchExc($rsTmp->getMessage());
            return false;
        }

Please help us help you.

* check if there is a function called query() in the file or in include files, if any.
* post the content of the query function.
* has PEAR been setup as per instruction i.e. is it in a place where PHP can find it?

OK i found the following in common.php in /usr/share/pear/DB

Code:

// }}}
    // {{{ query()

    /**
     * Send a query to the database and return any results with a
     * DB_result object.
     *
     * @access public
     *
     * @param string $query  the SQL query or the statement to prepare
     * @param string $params the data to be added to the query
     * @return mixed a DB_result object or DB_OK on success, a DB
     *                error on failure
     *
     * @see DB::isError
     * @see DB_common::prepare
     * @see DB_common::execute
     */
    function &query($query, $params = array()) {
        if (sizeof($params) > 0) {
            $sth = $this->prepare($query);
            if (DB::isError($sth)) {
                return $sth;
            }
            $ret = $this->execute($sth, $params);
            $this->freePrepared($sth);
            return $ret;
        } else {
            $result = $this->simpleQuery($query);
            if (DB::isError($result) || $result === DB_OK) {
                return $result;
            } else {
                return new DB_result($this, $result);
            }
        }
    }

strangely DB.php (which is the include for the class.news.php file) does not contain an include for common.php
PEAR has been setup with the installatino script provided and has also had the includes for it included in the .htaccess and is a default include shown in phpinfo()

What is going on here?

I'm stumped by the & in the function definition

. Wait for one of the elders to respond to your question.

You could try your luck on the PHP forums at - http://www.phpbuilder.com/, http://www.sitepointforums.com/.

Sorry couldn't be of any help. If you do resolve the problem, please post the answers here.

hi, i don't know PEAR but i know in php/mysql if your sql command has the wrong syntax it gives you an error "mysql_query() not a function" or something almost exactly like your error. doulbe check tom ake sure the $sql command you are using is actually correct.

pnh73 · 09-26-2003, 12:30 PM

The sql query, AFAIK is correct as this is code that I got from a book and I have seen a working example at http://wrox.mediatemple.net

sk8guitar · 09-26-2003, 06:13 PM

did you try the sql query in the sql prompt?

pnh73 · 09-27-2003, 08:03 AM

Running the query, which is

Code:

SELECT news_type_id,news_type FROM holiday_news_types

works fine.

Going to inspect logs etc. see if i can find anthing there. I have seen hints that it may be DSN difinition is incorrect, but i have checked and it seems to be fine.

Help? Does any1 know anything more?

if mysql_query() doesnt work, then maybe php wasnt compiled with mysql.
