Bug #85784

Updated by Georg Ringer over 5 years ago

I added my own column with fieldInformation to TCA using this code 

 <pre> 
 //create columns 
 $column = array ( 
     'keywords' => [ 
         'exclude' => '0', 
         'label' => 'myLabel', 
         'config' => [ 
             'type' => 'text', 
             'fieldInformation' => [ 
                 'html' => 'Zeile 1',  
             ], 
         ], 
     ], 
 ); 



 //add column to TCA 
 \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addTCAcolumns( 
     'sys_category', 
     $column 
     ); 

 //add Field to Palette 
 \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addFieldsToAllPalettesOfField( 
     'sys_category',  
     'description',  
     'keywords'); 
 </pre> 

 DependencyOrderingService threw an error. 

 <pre>

 Check if $dependencies[$id][$beforeKey] and $dependencies[$id][$afterKey] are set before iterating. 

 <pre> 
 98: foreach ($identifiers as $id) { 
 99:     //Check if $dependencies[$id][$beforeKey] is set before iterating. 
 100:    if (isset($dependencies[$id][$beforeKey])) { 
 101:      foreach ($dependencies[$id][$beforeKey] as $beforeId) { 
 102:        $dependencyGraph[$beforeId][$id] = true; 
 103:      } 
 104:    } 
 105:    //Check if $dependencies[$id][$afterKey] is set before iterating. 
 106:    if (isset($dependencies[$id][$afterKey])) { 
 107:      foreach ($dependencies[$id][$afterKey] as $afterId) { 
 108:        $dependencyGraph[$id][$afterId] = true; 
 109:      } 
 110:    } 
 111:} 
 </pre> 


 Check if $dependency is array. in case of fieldInformation it only is a string 

 <pre> 
 271: protected function prepareDependencies(array $dependencies, $beforeKey = 'before', $afterKey = 'after') 
 272: { 
 273:     $preparedDependencies = []; 
 274:     foreach ($dependencies as $id => $dependency) { 
 275        //check if $dependency is array 
 276:       if (is_array($dependency)) { 
 277:         foreach ([ $beforeKey, $afterKey ] as $relation) { 
 278:           if (!isset($dependency[$relation]) || !is_array($dependency[$relation])) { 
 279:             $dependency[$relation] = []; 
 280:           } 
 281:           // add all missing, but referenced identifiers to the $dependency list 
 282:           foreach ($dependency[$relation] as $dependingId) { 
 283:             if (!isset($dependencies[$dependingId]) && !isset($preparedDependencies[$dependingId])) { 
 284:               $preparedDependencies[$dependingId] = [ 
 285:                 $beforeKey => [], 
 286:                 $afterKey => [] 
 287:               ]; 
 288:             } 
 289:           } 
 290:         } 
 291:       } 
 292:       $preparedDependencies[$id] = $dependency; 
 293:     } 
 294:     return $preparedDependencies; 
 295: }
