Fatal error: Call to a member function on a non-object in /var/www/crmctt/someDir/someName.php on line 153

 

the code will be some thing like this:

 

<?php
/*
	//
	// IncidentModel.php
	// this model class stores only business logic
	// data is stored in the entity class
	//

//someCode....

 

the line 153 will be:

 

mysql_real_escape_string($this->incident->startDateTime->GetTimestamp(), $this->dao->GetDBConn()),

 

can anyone help me on this?  ???

That means that something you thought is an object actually isn't one.  Try checking each one individually until you find the culprit.  You can use var_dump(), and/or is_object().  Put your checks on the line before the line with the error.  You'll need to check $this->incident, then $this->incident->startDateTime, and so on.

hi btherl, thx for ur quick reply.

 

i hv used the var_dump() to check on the error line. this error come out:

 

Parse error: syntax error, unexpected T_STRING in /var/www/someDir/someName.php on line 154

 

line 154 still refer to the same error line before and i got no idea what is it.

[emehrkay]

i dotn know if you can use commas in the mysql_real_escape_string function

replace them with periods

[btherl]

Can you post the code that gave you the syntax error?

[ikanku15]

here is the code that give me the syntax error

 

mysql_real_escape_string($this->incident->startDateTime->GetTimestamp(), $this->dao->GetDBConn()),

[ikanku15]

this code is more detail

 

$this->dao->ExecuteQuery(sprintf("INSERT INTO `incident`" . 
				" (`fID`, `uID`, `inTypeID`, `inStartDateTime`, `inEndDateTime`, `inReason`, `inDescription`, `inEmail`, `inLastUpdate`)" .
				" VALUES(%d, %d, %d, %d, %d, '%s', '%s', '%s', %d)",
				mysql_real_escape_string($this->incident->fqdn->GetFID(), $this->dao->GetDBConn()),
				mysql_real_escape_string($this->user->GetID(), $this->dao->GetDBConn()),
				mysql_real_escape_string($this->incident->type->GetTypeID(), $this->dao->GetDBConn()),
				var_dump() // <---- i have added this to the code to check
				mysql_real_escape_string($this->incident->startDateTime->GetTimestamp(), $this->dao->GetDBConn()), // <---- the code line that generate the error
				mysql_real_escape_string($this->incident->endDateTime->GetTimestamp(), $this->dao->GetDBConn()),
				mysql_real_escape_string($this->incident->GetReason(), $this->dao->GetDBConn()),
				mysql_real_escape_string($this->incident->GetDescription(), $this->dao->GetDBConn()),
				mysql_real_escape_string($this->incident->GetEmail(), $this->dao->GetDBConn()),
				mysql_real_escape_string(time(), $this->dao->GetDBConn()))); 

[btherl]

ikanku, remove the var_dump() you added and add this code outside your ExecuteQuery (on the line before):

 

print "\$this->incident looks like this: ";var_dump($this->incident);print "<br>\n";
print "\$this->incident->startDateTime looks like this: ";var_dump($this->incident->startDateTime);print "<br>\n";
$this->dao->ExecuteQuery( ...

 

And see what it outputs.  It should tell you exactly which thing is not an object.  Then you need to work out why it isn't an object.
