我想补充的名字领域的一些附加数据（Laravel 5.3）

Question

我已创建使用复制在这里重复行是我的功能

public function copy($id){ 

    $task = Task::find($id); 
    $copy = $task->replicate(); 
    $copy->save(); 
    session()->flash('msg','successfully Copied!'); 
} 

我想，在复制我的名字字段应该改变

任务1 - 复制

如果我做第二个副本，它应该是为

任务1 - 副本2

请帮我使其相应

Answer 1

你可以尝试这样的

$task = Task::find($id); 

$copy = $task->replicate(); 
$copy->name = $copy->name.'2'; 
$copy->save(); 

Answer 2

像这样的东西应该工作

$task = Task::find($id); 

$copy = $task->replicate(); 

// If the name contains the word 'copy' create the next one 
if (str_is('copy', $copy->name)){ 

    //Get the last word 
    $words = explode(' ', $copy->name); 
    $last_word = array_pop($words); 

    // If the last word is 'copy' create the right number, else it's the first copy 
    if ($last_word == 'copy'){ 
     $copy->name = str_finish($copy->name, ' 2'); 
    } else { 
     $number = strval(intval($last_word) + 1); 
     $copy->name = str_finish(implode(" ", $words), ' ' . $number); 
    } 
// Else create the first one 
} else { 
    $copy->name = str_finish($copy->name, ' - copy'); 
} 

$copy->save();
