XML error Open quote is expected for attribute "value" when programming in PHP
提问by J Noel
Hello and thank you for your help,
您好，感谢您的帮助，
I am using PHP to write an XML request, the problem I am having is when I use the variable in the value field, it returns an error. However when I write in the value manually it works perfectly. Under field name='Serial_Number' you will see the $MREPSerial is the variable, let's assume that in the PHP we have $MREPSerial = 'A-000-1042'; The below XML would give an error. However if i were to replace $MREPSerial with just the value in the XML it would be successful. Any help would be greatly appreciated. Thank you!

$MREPSerial = htmlspecialchars(strtoupper($_POST['NSMREP']));
echo "Hi".$MREPSerial;

... the return response on echo (including the XML i echoed)
... echo 的返回响应（包括我回显的 XML）
A-000-1012HI! <?xml version="1.0" encoding="UTF-8" ?>
<response><errorlist><error><code>2830</code><message><![CDATA[Open quote is expected for attribute "value" associated with an element type "field".]]></message></error></errorlist></response>
the return response on echo if i change it to '".$MREPSerial." is:
如果我将其更改为 '".$MREPSerial."，则回显的返回响应。是：
A-000-1012HI! <?xml version="1.0" encoding="UTF-8" ?>
<response><result><form name="MREP"><update><criteria><field name="Serial_Number" compOperator="Equals" value=""></field><reloperator>AND</reloperator><field name="MREP_Type" compOperator="Equals" value="0"></field></criteria><newvalues><field name="Is_being_Used"><value><![CDATA[TRUE]]></value></field></newvalues> <status>Failure, No Records Found With Specified Criteria</status></update></form></result></response>

You need quotes around the value attribute's actual value, like this:
您需要在 value 属性的实际值周围加上引号，如下所示：
<field name='Serial_Number' compOperator='Equals' value='{$MREPSerial}'></field>

just saw your ";close tag...
刚刚看到你的";关闭标签...
try this for that line
为那条线试试这个
<field name='Serial_Number' compOperator='Equals' value='".$MREPSerial."'></field>
