muckv Posted November 10, 2008 Share Posted November 10, 2008 hey, when I call the method get_copyright() the array $meta becomes null instead op returning the value of $meta['copyright'] Everything goes well in the constructor, but when that method is called (see above) does anybody see what I did wrong <?php class IPTC{ var $meta; var $image; function __construct($image){ $meta=array(); $this->meta=$meta; $this->image=$image; $meta = array( 'credit' => '', 'caption' => '', 'created_timestamp' => 0, 'copyright' => '', 'title' => '', ); $size=getimagesize($image,$info); if ( isset ($info['APP13'])) { $iptc=iptcparse($info['APP13']); if ( !empty($iptc['2#110'][0]) ) $meta['credit'] = utf8_encode(trim($iptc['2#110'][0])); elseif ( !empty($iptc['2#080'][0]) ) $meta['credit'] = utf8_encode(trim($iptc['2#080'][0])); if ( !empty($iptc['2#055'][0]) and !empty($iptc['2#060'][0]) ) $meta['created_timestamp'] = strtotime($iptc['2#055'][0] . ' ' . $iptc['2#060'][0]); if ( !empty($iptc['2#120'][0]) ) // caption $meta['caption'] = utf8_encode(trim($iptc['2#120'][0])); if ( !empty($iptc['2#116'][0]) ) // copyright $meta['copyright'] = utf8_encode(trim($iptc['2#116'][0])); if ( !empty($iptc['2#005'][0]) ) // title $meta['title'] = utf8_encode(trim($iptc['2#005'][0])); } } function get_credit(){ return $meta['credit']; } function get_timestamp(){ return $meta['created_timestamp']; } function get_caption(){ return $meta['caption']; } function get_copyright(){ return $meta['copyright']; } function get_title(){ return $meta['title']; } } $image_info = new IPTC('suzy1.jpg') or die ('kan geen iptc gegevens extracten uit image'); echo $image_info->get_copyright()or die('geen copyright beschikbaar'); Link to comment https://forums.phpfreaks.com/topic/132113-solved-class-variable-becomes-null/ Share on other sites More sharing options...
ranjuvs Posted November 10, 2008 Share Posted November 10, 2008 Try this <?php <?php class IPTC{ var $meta; var $image; function __construct($image){ $this->image=$image; $this->meta = array( 'credit' => '', 'caption' => '', 'created_timestamp' => 0, 'copyright' => '', 'title' => '', ); $size=getimagesize($image,$info); if ( isset ($info['APP13'])) { $iptc=iptcparse($info['APP13']); if ( !empty($iptc['2#110'][0]) ) $this->meta['credit'] = utf8_encode(trim($iptc['2#110'][0])); elseif ( !empty($iptc['2#080'][0]) ) $this->meta['credit'] = utf8_encode(trim($iptc['2#080'][0])); if ( !empty($iptc['2#055'][0]) and !empty($iptc['2#060'][0]) ) $this->meta['created_timestamp'] = strtotime($iptc['2#055'][0] .

bobbinsbro Posted November 10, 2008 Share Posted November 10, 2008 the array $info doesn't exist, so isset ($info['APP13']) returns false, so the if block isn't executed, so $meta['copyright'] isn't created/populated in the constructor.

muckv Posted November 10, 2008 Author Share Posted November 10, 2008 Well, Still the same problem, the if structure does get executed cause I follow it while debugging I can see the correct value in meta['copyright'] until the method gets called <?php class IPTC{ var $meta; var $info; function __construct($image){ $this->image=$image; $this->meta=array( 'credit' => '', 'caption' => '', 'created_timestamp' => 0, 'copyright' => '', 'title' => '', ); $size=getimagesize($image,$info); $this->info=$info; if ( isset ($info['APP13'])) { $iptc=iptcparse($info['APP13']); if ( !empty($iptc['2#110'][0]) ) $meta['credit'] = utf8_encode(trim($iptc['2#110'][0])); elseif ( !empty($iptc['2#080'][0]) ) $meta['credit'] = utf8_encode(trim($iptc['2#080'][0])); if ( !empty($iptc['2#055'][0]) and !empty($iptc['2#060'][0]) ) $meta['created_timestamp'] = strtotime($iptc['2#055'][0] .

bobbinsbro Posted November 10, 2008 Share Posted November 10, 2008 well, i just ran the code you pasted (had to fix it to use $this), and i added this line: echo "in if"; on line 26, right after this: $iptc=iptcparse($info['APP13']); and the text "in if" does not display. as i said, $info['APP13'] does not get set/declared/initialized anywhere in the class, and so the if(isset($info['APP13'])) does not execute.

trq Posted November 11, 2008 Share Posted November 11, 2008 return $meta['copyright']; Needs to be.... return $this->meta['copyright']; for starters. All your methods need changing.

muckv Posted November 11, 2008 Author Share Posted November 11, 2008 this is the content of image_info so you see the array $meta is empty but why? <?php class IPTC{ var $meta; var $info; function __construct($image){ $this->image=$image; $this->meta=array( 'credit' => '', 'caption' => '', 'created_timestamp' => 0, 'copyright' => '', 'title' => '', ); $size=getimagesize($image,$info); $this->info=$info; if ( isset ($info['APP13'])) { $iptc=iptcparse($info['APP13']); if ( !empty($iptc['2#110'][0]) ) $meta['credit'] = utf8_encode(trim($iptc['2#110'][0])); elseif ( !empty($iptc['2#080'][0]) ) $meta['credit'] = utf8_encode(trim($iptc['2#080'][0])); if ( !empty($iptc['2#055'][0]) and !empty($iptc['2#060'][0]) ) $meta['created_timestamp'] = strtotime($iptc['2#055'][0] .

wildteen88 Posted November 11, 2008 Share Posted November 11, 2008 You are setting the $this->meta variable in correctly. Here if ( !empty($iptc['2#110'][0]) ) $meta['credit'] = utf8_encode(trim($iptc['2#110'][0])); elseif ( !empty($iptc['2#080'][0]) ) $meta['credit'] = utf8_encode(trim($iptc['2#080'][0])); if ( !empty($iptc['2#055'][0]) and !empty($iptc['2#060'][0]) ) $meta['created_timestamp'] = strtotime($iptc['2#055'][0] . ' ' . $iptc['2#060'][0]); if ( !empty($iptc['2#120'][0]) ) // caption $meta['caption'] = utf8_encode(trim($iptc['2#120'][0])); if ( !empty($iptc['2#116'][0]) ) // copyright $meta['copyright'] = utf8_encode(trim($iptc['2#116'][0])); if ( !empty($iptc['2#005'][0]) ) // title $meta['title'] = utf8_encode(trim($iptc['2#005'][0])); } You're populating your $meta array. $this->meta and $meta are not the same. You'll need to change all instances of $meta to $this->meta or add the following line after the above block of code $this->meta = $meta; Link to comment https://forums.phpfreaks.com/topic/132113-solved-class-variable-becomes-null/#findComment-687924 Share on other sites More sharing options...
