    <p>I'm new to PHP. i am trying to create some html code within a php function as below.</p> <hr> <pre><code>$str .="&lt;/div&gt; &lt;div class='cls_setpadding'&gt; &lt;form method='get' action='homepage.php'&gt; &lt;div class='cls_caller_options'&gt; &lt;select name='test'&gt; &lt;option value='allcaller'&gt;".getResourceStrings('msg_allcaller',$lng)."&lt;/option&gt; &lt;option value='specialcaller'&gt;".getResourceStrings('msg_splcaller',$lng)."&lt;/option&gt; &lt;/select&gt;&lt;br /&gt; &lt;/div&gt; &lt;div class='cls_msg_splcaller'&gt;"; $str .= getResourceStrings('msg_spcallaer',$lng); $str .=" &lt;/div&gt; &lt;div style='padding-top:2%'&gt;&lt;/div&gt; &lt;div class='cls_search_box'&gt; &lt;input type='hidden' name='function' value='Buysuccess' /&gt; &lt;input type='hidden' name='vcode' value='".$vcode."' /&gt;"; if($testmsisdnheader != ""){ $msisdn_header = getheader(); $str .="&lt;input type='hidden' name='".$msisdn_header."' value='".$msisdn."' /&gt;"; } $str .=" &lt;input type='text' onkeydown='return ( event.ctrlKey || event.altKey || (47&lt;event.keyCode &amp;&amp; event.keyCode&lt;58 &amp;&amp; event.shiftKey==false) || (95&lt;event.keyCode &amp;&amp; event.keyCode&lt;106) || (event.keyCode==8) || (event.keyCode==9) || (event.keyCode&gt;34 &amp;&amp; event.keyCode&lt;40) || (event.keyCode==46) )' name='cbsmsisdn' maxlength='12' disabled='true'/&gt;&lt;br /&gt; &lt;div style='padding-top:1%'&gt;&lt;/div&gt; &lt;input type='submit' value='Submit' /&gt;&lt;br /&gt; &lt;/div&gt; &lt;/form&gt; &lt;/div&gt;"; </code></pre> <hr> <p>Now I want to enable/disable the text box on the basis of value selected in drop down.</p> <p>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'.</p> <p>I wasn't able to enable the text box on the basis of value selected in drop down.</p> <p>Any help would be highly appreciated.</p> <p>Thanks! Bobby.</p>

    2. COI have added disabled='true'. If I remove this the text box becomes editable. However, what I want is to put a condition or any other way to decide what value has been chose. On the basis of that value, I will construct the string with parameter disabled='true'. If there is any other way to do this, I'm perfectly okay with it. But, I do not want to use java script unless there is no other option to do it in PHP.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
