I'm new to PHP. i am trying to create some html code within a php function as below.

$str .="</div>
                <div class='cls_setpadding'>
                    <form method='get' action='homepage.php'>
                    <div class='cls_caller_options'>
                        <select name='test'>
                            <option value='allcaller'>".getResourceStrings('msg_allcaller',$lng)."</option>
                            <option value='specialcaller'>".getResourceStrings('msg_splcaller',$lng)."</option>
                        </select><br />
                    </div>
                    <div class='cls_msg_splcaller'>";
        $str .=      getResourceStrings('msg_spcallaer',$lng);          
        $str .="    </div>
                    <div style='padding-top:2%'></div>
                    <div class='cls_search_box'>
                    <input type='hidden' name='function' value='Buysuccess' />
                    <input type='hidden' name='vcode' value='".$vcode."' />";
                    if($testmsisdnheader != ""){
                        $msisdn_header = getheader();
                        $str .="<input type='hidden' name='".$msisdn_header."' value='".$msisdn."' />";
                    }

        $str .="    <input type='text' onkeydown='return ( event.ctrlKey || event.altKey 
                    || (47<event.keyCode && event.keyCode<58 && event.shiftKey==false) 
                    || (95<event.keyCode && event.keyCode<106)
                    || (event.keyCode==8) || (event.keyCode==9) 
                    || (event.keyCode>34 && event.keyCode<40) 
                    || (event.keyCode==46) )' name='cbsmsisdn' maxlength='12' disabled='true'/><br />
                    <div style='padding-top:1%'></div>
                    <input type='submit' value='Submit' /><br />
                    </div>
                </form>
            </div>";

Now I want to enable/disable the text box on the basis of value selected in drop down.

Here i like to put a condition where if the option value equals 'allcaller' the text box should be disabled which is actually happening. But I want to enable the same text box in case option value equals to 'specialcaller'.

I wasn't able to enable the text box on the basis of value selected in drop down.

Any help would be highly appreciated.

Thanks! Bobby.

我有两个可能的解决方案给你。

  1. 正如您在评论中提到的那样，您不想使用 java 脚本，因为它是一个 WAP 门户，但如果不使用 javascript，他们没有其他方法可以做到这一点。我可以向您推荐一种方法，您可以要求用户提交他的下拉结果。根据该结果，您可以启用或禁用下一页上的文本框。

  2. 否则去javascript。
