Etable/formType/file

(一)製作表單元素類別

formsome.php 中

class XoopsFormUploadFile extends XoopsFormElement {
	function XoopsFormUploadFile($caption, $name){	// 提示、後傳變數名
		$this->setCaption($caption);
		$this->setName($name);
	}
	function render(){
		return "<input type='file' name='".$this->getName()."' id='".$this->getName()."'".$this->getExtra()." />".$this->getExtra('2');
	}
}
class XoopsFormFile extends XoopsFormElementTray{
	function XoopsFormFile($caption, $name, $value='', $paths=array('.'=>'當前路徑')){
		$this->XoopsFormElementTray($caption,'  ');
		$pathSelect=new XoopsFormSelect('路徑:',$name.'[path]',$value='');// 產生選單物件並指定預選值
		$pathSelect->addOptionArray($paths);
		$this->addElement($pathSelect);// 將選單物件放入表單
		$fileUpload=new XoopsFormUploadFile('請選檔:', $name.'[fileName]');
		$this->addElement($fileUpload);// 將選單物件放入表單
	}
}

(二)addElements($i,$value)

加表單元素類型為 file 則

$j=new XoopsFormFile($this->fields[$i]['colalias'],'f['.$this->fields[$i]['as_name'].']['.$this->fields[$i]['colname'].']',str_replace("'",''',str_replace("&",'&',$value)),$this->formType["$lc_name"][1]['paths']);
$this->form->addElement($j,(($this->fields[$i]['formValidate']==0)?'0':'1'));
$this->form->addElement(new XoopsFormHidden('uploadFileField',$lc_name,0));
$this->form->addElement(new XoopsFormHidden('uploadFilePath',$value,0));

(三)新增 login.php 中可以後送檔案的 javascript 函式 postFormData(…)

function postFormData(formID,dataSource,divID){	// 以 fetch 發POST請求，可以上傳檔案，等於原來的 sendFormData＋postData
	var formData = new FormData();
	for(var i=0;i<document.getElementById(formID).elements.length;i++){
		if(document.getElementById(formID).elements[i].type=='checkbox' || document.getElementById(formID).elements[i].type=='radio'){
			if(document.getElementById(formID).elements[i].type=='checkbox'){	// 處理核取方塊，checked回傳值，沒checked回傳空字串
				if(document.getElementById(formID).elements[i].checked==true){formData.append(document.getElementById(formID).elements[i].name,document.getElementById(formID).elements[i].value);}
				else{formData.append(document.getElementById(formID).elements[i].name,'');}
			}else{									// 處理按鈕，checked回傳值，否則跳過
				if(document.getElementById(formID).elements[i].checked==true){formData.append(document.getElementById(formID).elements[i].name,document.getElementById(formID).elements[i].value);}
			}
		}
		else if(document.getElementById(formID).elements[i].type=='hidden'){formData.append(document.getElementById(formID).elements[i].name,document.getElementById(formID).elements[i].value);}
		//新增檔案資料
		else if(document.getElementById(formID).elements[i].type=='file'){formData.append(document.getElementById(formID).elements[i].name,document.getElementById(formID).elements[i].files[0]);}
		else{formData.append(document.getElementById(formID).elements[i].name,document.getElementById(formID).elements[i].value);}
	}
	fetch(dataSource, {method:'POST',body:formData}).then((response)=>{return response.text();}).then((responseText)=>{document.getElementById(divID).innerHTML=responseText;onAjax(a);});
}

(四)修改 etable.php 中的 javascript 函式 checkFormlist(…)

if($field['formType'][0]=='file'){$str.="\t\telse if(!(/".$field['formValidate'][0]."/.test(document.getElementsByName('f[".$field['as_name']."][".$field['colname']."][path]')[0].value) && (/".$field['formValidate'][0]."/.test(document.getElementsByName('f[".$field['as_name']."][".$field['colname']."][fileName]')[0].value)))){alert(\"".$field['formValidate'][1]."\");}\n";}

(六)main() / 單筆資料前置處理 / 編畢、刪一筆

「$action=='ins_ed'」或「$action=='inss'」：已透過 fieldValue2sqlStr 函式處理

「$action=='erase'」

if($action=='erase'){
	foreach($this->editables['erase'] as $as_name){
		foreach($this->formType as $k=>$v){
			if($v[0]=='file'){
				unlink(mysqli_result(DB::queryF("select `$k` from ".$this->tables["$as_name"]['t_name']." where 1 ".$this->decode($this->rid["$as_name"])." limit 1"),0,0));
			}
		}
		DB::queryF("delete from ".$this->tables["$as_name"]['t_name']." where 1 ".$this->decode($this->rid["$as_name"])." limit 1");	// by jj now
	}
}

「$action=='edited'」：已透過 fieldValue2sqlStr 函式處理
