Php: modify attribute html tag

Question

I have these html tags:

 <select name="ct" id="ct">
        <option value="-1">Tutte</option>
        <option value="1">Da verificare</option>
        <option value="2">Verificate</option>
        <option value="3">Approvate</option>
        <option value="4">Respinte</option>
        <option value="5">Pubblicate</option>
        <option value="6">Scadute</option>
        <option value="7">Proposte</option>
        <option value="8">Rifiutate</option>
        <option value="9">Ritirate</option>
        <option selected="selected" value="7,8,1">Proposte / Rifiutate / Da verificare</option>
   </select>

I want to change the attribute value of the selected option (which contains "7,8,1") to value="-1", so it will look like:

<option selected="selected" value="-1">Proposte / Rifiutate / Da verificare</option>

I tried with:

$dom_richieste->getElementsByTagName('options')->getAttribute('value').value="-1";

But that's not working...

$dom_richieste->getElementsByTagName('options')->getAttribute('value').value="-1"; makes no sense and is invalid in both Javascript and PHP. Show how you set $dom_richieste. — MonkeyZeus

You can use $("#ct option[value='7,8,1']").val("-1");

$("#ct option[value='7,8,1']").val("-1");
console.log($("#ct").val());

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="ct" id="ct">
        <option value="-1">Tutte</option>
        <option value="1">Da verificare</option>
        <option value="2">Verificate</option>
        <option value="3">Approvate</option>
        <option value="4">Respinte</option>
        <option value="5">Pubblicate</option>
        <option value="6">Scadute</option>
        <option value="7">Proposte</option>
        <option value="8">Rifiutate</option>
        <option value="9">Ritirate</option>
        <option selected="selected" value="7,8,1">Proposte / Rifiutate / Da verificare</option>
   </select>

I suggest you to check how you created this drop down, and if possible replace there instead after creating drop down.

This is very specific to the question - make it more generic by searching the 'selected' attribute

If I understand correctly you are need something like:

foreach ($dom->getElementsByTagName('option') as $item) {
    if ($item->getAttribute('selected') == "selected")
        $item->setAttribute("value", "-1");
}

This way you pass on your option items and set the value of the selected ones

You have used getElementsByTagName('options') in your code and no tag available with name options. Instead you should use correct tag name option.
