PHP自动生成表单代码分享

在PHP开发过程中，我们有时候会遇到表单不固定的情况，需要在程序运行过程中动态生成，这里分享一个PHP自动创建表单的类给大家

Form.php

action=$action; $this->method=$method; } function form_start(){ $text="

action}\" method=\"{$this->method}\""; if($this->class!==""){ $text.=" class=\"{$this->class}\""; } if ($this->enctype!=="") { $text.=" enctype=\"{$this->enctype}\""; } if($this->id!==""){ $text.=" id=\"{$this->id}\""; } if($this->name!==""){ $text.=" name=\"{$this->name}\""; } $text.=">\n"; if($this->layout==true){ $text.="\n"; } return $text; } function form_end(){ if ($this->layout==true) { $text="\t\n"; $text.="

\n"; }else { $text="\n"; } return $text; } //文本框函数 function form_text($name,$id,$label_name,$label_for,$value=""){ $text="\n"; $label=$this->form_label($label_name,$label_for); $form_item=$this->form_item($label,$text); return $form_item; } //密码框函数 function form_passwd($name,$id,$label_name,$label_for,$value=""){ $text="\n"; $label=$this->form_label($label_name,$label_for); $form_item=$this->form_item($label,$text); return $form_item; } //隐藏域函数 function form_hidden($name,$id,$label_name,$label_for,$value=""){ $text="\n"; $label=$this->form_label($label_name,$label_for); $form_item=$this->form_item($label,$text); return $form_item; } //文件域函数 function form_file($name,$id,$label_name,$label_for,$size=""){ $text="\n"; $label=$this->form_label($label_name,$label_for); $form_item=$this->form_item($label,$text); return $form_item; } //复选框函数 function form_checkbox($name,$label=array(),$label_name,$label_for=""){ $i=0; $text=array(); foreach ($label as $id=>$value){ $text[$i]=""; $text[$i].="{$value}"; $i++; } $label=$this->form_label($label_name,$label_for); $form_item=$this->form_item($label,$text); return $form_item; } //单选框函数 function form_radio($name,$label=array(),$label_name,$label_for=""){ $i=0; $text=array(); foreach ($label as $id=>$value){ $text[$i]=""; $text[$i].="{$value}"; $i++; } $label=$this->form_label($label_name,$label_for); $form_item=$this->form_item($label,$text); return $form_item; } //下拉菜单函数 function form_select($id,$name,$options=array(),$selected=false,$label_name,$label_for,$onchange=""){ if($onchange!==""){ $text="\n"; } else{ $text="\n"; } foreach ($options as $value=>$key){ if($selected==$value){ $text.="\t{$key}\n"; }elseif ($selected===false) { $text.="\t{$key}\n"; } } $text.=""; $label=$this->form_label($label_name,$label_for); $form_item=$this->form_item($label,$text); return $form_item; } //多选列表函数 function form_selectmul($id,$name,$size,$options=array(),$label_name,$label_for){ $text="\n"; foreach ($options as $value=>$key){ $text.="\t{$key}\n"; } $text.="\n"; $label=$this->form_label($label_name,$label_for); $form_item=$this->form_item($label,$text); return $form_item; } //按钮函数 function form_button($id,$name,$type,$value,$onclick=""){ $text="".$value; $text.="\n"; if($this->layout==true){ $form_item="\n\t {$text}\n\n"; }else { $form_item=$text; } return $form_item; } //文本域函数 function form_textarea($id,$name,$cols,$rows,$label_name,$label_for,$value=""){ $text="{$value}\n"; $label=$this->form_label($label_name,$label_for); $form_item=$this->form_item($label,$text); return $form_item; } //文字标签函数 function form_label($text,$for){ if($for!==""){ $label="{$text}："; }else { $label=$text."："; } return $label; } function form_item($form_label,$form_text){ switch ($this->layout){ case true: $text="\n"; $text.="\t"; $text.=$form_label; $text.="\n"; $text.="\t"; $text.=$form_text; $text.="\n"; $text.="\n"; break; case false: $text=$form_label; $text.=$form_text; break; } return $text; } function CreateForm($form_item=array()){ echo $this->form_start(); foreach ($form_item as $item){ echo $item; } echo $this->form_end(); } } ?>
