PHP SQL SELECT puis UPDATE la valeur

Question

J'ai un problème.

$db = JFactory::getDBO(); 

$res2 = $_data['DateSubmitted']; 
//res2 returns 2014-08-31 12:03:02 
$res3 = $_data['UserIp']; 
//res3 returns 109.173.20.143 for example 

$resdate = date('Y-m-d H:i:s', strtotime($res2)); 

$SubmId = $db->query("SELECT `SubmissionId` FROM `rrr_submissions` WHERE `FormId` = '20' AND `DateSubmitted`='".$resdate."' AND `UserIp`='".$res3."'"); 

$db->setQuery("UPDATE `rrr_submission_values` SET `FieldValue` = '".$SubmId."' WHERE `FieldName`='7_Status' AND `SubmissionId`='5682'"); 

$db->query(); 

Dans rrr_submissions:

• submissionId est INT (11) AUTO_INCREMENT
• formID est INT (11)
• DateSubmitted est datetime
• userip est varchar (15)

En rrr_submission_values:

• FieldValue est le texte
• FieldName est un texte
• submissionId est int (11)

Qu'est-ce que je fais mal? Dans le résultat, je vois "1" dans FieldValue.

Essayez de charger la ligne de résultat, puis appelez la valeur du champ.

$db = JFactory::getDBO(); 

$res2 = $_data['DateSubmitted']; 
//res2 returns 2014-08-31 12:03:02 
$res3 = $_data['UserIp']; 
//res3 returns 109.173.20.143 for example 

$resdate = date('Y-m-d H:i:s', strtotime($_data['DateSubmitted'])); 

$SubmId = $db->query("SELECT `SubmissionId` FROM `rrr_submissions` WHERE `FormId` = '20' AND `DateSubmitted`='".$resdate."' AND `UserIp`='".$res3."'"); 

$row = $db->loadRow(); 

$SubmId = $row['SubmissionId']; 

$db->setQuery("UPDATE `rrr_submission_values` SET `FieldValue` = '".$SubmId."' WHERE `FieldName`='7_Status' AND `SubmissionId`='5682'"); 

$db->query();
