Question

我有一个数组，比如它在{am。{}中的$_FILES。

Array ( [ANTI-HAV__TOTAL] => Array ( [name] => Array ( [0] => Firefox_wallpaper1.png [1] => Firefox_wallpaper2.png ) [type] => Array ( [0] => image/png [1] => image/png ) [tmp_name] => Array ( [0] => /tmp/phpr92AvZ [1] => /tmp/phpxmzia3 ) [error] => Array ( [0] => 0 [1] => 0 ) [size] => Array ( [0] => 353750 [1] => 353750 ) ) )

但是当我尝试使用像

这样的foreach时

foreach($_FILES['ANTI-HAV__TOTAL']['name'] as $value1)

它说

Warning: Invalid argument supplied for foreach()

我该如何解决这个问题？

这是我的表格

<?php
$myresult .= '<div class=\'fieldForm\'>';
$myresult .= '<form id=\'lab_form\' enctype=\'multipart/form-data\' method=\'POST\' action =\''.$this->url(array('controller'=>'lab', 'action' =>'uploadsave')).'\'>';
$myresult .= '<fieldset>';
$myresult .= '<legend>Lab Upload Form</legend>';
foreach($labtests_break as $key => $value)
{
$nvalue = str_replace(' ','__',trim($value));
$nvalue = str_replace('(','___',trim($nvalue));
$nvalue = str_replace(')','____',trim($nvalue));
if(!in_array($value,$gotImages2))
{     
$myresult .= '<div class=\'field50Pct\'>';
/*$myresult .= '<input type=\'button\' id=\''.$nvalue.'Add\'  value=\'Add Another '.$value.' Image\' onclick=\'addElement(this.id)\' />';
$myresult .= '<input type=\'button\' id=\''.$nvalue.'Del\'  value=\'Remove'.$value.' Image\' onclick=\'removeElement(this.id)\' disabled=\'disabled\/>';*/
$myresult .= '</div>';
$myresult .= '<div class=\'clear\'></div>';
$myresult .= '<div class=\'clear\'></div>';
$myresult .= '<div class=\'field50Pct\'>';
$myresult .= '<div class=\'fieldItemLabel\'>';
$myresult .= '<label for=\'\'>'.$value.'</label>';
$myresult .= '</div>';
$myresult .= '<div class=\'fieldItemValue\'>';
$myresult .= '<div id=\''.$nvalue.'input1\'  class=\''.$nvalue.'clonedInput\'>';
$myresult .= '<input type=\'file\' name=\''.$nvalue.'[]\'  id=\''.$nvalue.'1\' class="multi">';
//$myresult .= '<input type=\'button\' style=\'width:50px;padding:2px;margin-left:10px;\' value=\'Clear\'  onclick=\'clearField(this)\'/>';
$myresult .= '</div>';
$myresult .= '</div>';
$myresult .= '</div>';
$myresult .= '<div class=\'clear\'></div>';
}
}
$myresult .= '<input type=\'hidden\' name=\'visitId\'  value=\''.$visitId.'\' >';
$myresult .= '<input type=\'hidden\' name=\'patientId\'  value=\''.$patientId.'\' >';
$myresult .= '<input type=\'hidden\' name=\'tests\'  value=\''.$labtests.'\' >';
$myresult .= '<input type=\'submit\' value=\'upload\'>';
$myresult .= '</fieldset>';
$myresult .= '</form>';
$myresult .= '</div>';
echo $myresult;
?>

这是动作部分的控制器。

public function uploadsaveAction()
{
$this->view->homeId = "current";
        $this->view->homeUrl = $this->view->url(array('controller' => 'lab', 'action' =>'index'));

         $request = $this->getRequest();
if($request->isPost())
        {
                $visitId        = $_POST['visitId'];
                $patientId      = $_POST['patientId'];
                $tests          = $_POST['tests'];
                $tests_break    = explode(',',$tests);
                foreach($tests_break as $key=>$value)
                {

                        $nvalue = str_replace(' ','__',trim($value));
                        $nvalue = str_replace('(','___',trim($nvalue));
                        $nvalue = str_replace(')','____',trim($nvalue));

                        //for($i= 0; $i<=$limit ; $i++)
                        echo '<br/>';
                        print_r($_FILES);
                        echo '<br/>';
                        echo $nvalue;
                        foreach($_FILES[$nvalue]['name'] as $value1)
                        {
                        $key_found = array_search($value1, $_FILES[$nvalue]['name']); // $key = 2;

尝试

var_dump($_FILES['ANTI-HAV__TOTAL']);

首先查看您的密钥是否正确。
