Is $surveydata contains the key surveydata in it in the controller ? — Rikesh

Can you check var_dump($surveydata); on top of your view file ?\ — Rikesh

Please make sure,

You have data in your $surveydata.

If you are fetching results through

$resultSet->result() OR $resultSet->row(), then use $surveydata->SurveyTitle

And if you are fetching the results through:

$resultSet->result_array() OR $resultSet->row_array(), then use $surveydata['SurveyTitle]

Also, please make sure to check count of $surveydata

This is the data array (size=1) 0 => array (size=7) 'SurveyId' => string '145' (length=3) 'SurveyTitle' => string 'Survey 6' (length=8) 'SurveyIntro' => string 'Survey 6' (length=8) 'CreatedBy' => string 'm123456789' (length=10) 'DateCreated' => string '2014-04-04 04:08:12' (length=19) 'isDisabled' => string '0' (length=1) 'SurveyLink' => string '21491' (length=5)

It should be $surveydata[0]['SurveyId'], not $surveydata->SurveyId

Same for SurveyTitle It should be $surveydata[0]['SurveyTitle'], not $surveydata->SurveyTitle

same mistake you have done on next line also. Please correct wherever you have used $surveydata->SurveyId

In controller what is the output when you do print_r($surveydata);

vini Over a year ago

when i do var_dump i get this array (size=1) 0 => array (size=7) 'SurveyId' => string '145' (length=3) 'SurveyTitle' => string 'Survey 6' (length=8) 'SurveyIntro' => string 'Survey 6' (length=8) 'CreatedBy' => string 'm123456789' (length=10) 'DateCreated' => string '2014-04-04 04:08:12' (length=19) 'isDisabled' => string '0' (length=1) 'SurveyLink' => string '21491' (length=5)
