wap文本框动态赋值不显示解决办法

$searchKeys = array("言情","玄幻","都市","全本","校园","耽美","武侠","斗破苍穹");

$searchKeyLength = count($searchKeys);

$keyIndex = rand(0,$searchKeyLength-1);

<input emptyok="true" name="qs" value="<?php echo $searchKeys[$keyIndex];?>" size="10" />

 

 

结果文件框里面怎么也不显示动态取的值；

 

 

解决的办法：

 

$tmp = rand();

<input emptyok="true" 

   name="qs<?php echo $tmp;?>" value="<?php echo $searchKeys[$keyIndex];?>" size="10" /> 

postfield的值设定的时候：<postfield name="key" value="$(qs<?php echo $tmp;?>)" />
