Php read single-choice button radio Value
Copy codeThe Code is as follows:
<Html xmlns = "http://www.w3.org/1999/xhtml">
<Head>
<Meta http-equiv = "Content-Type" content = "text/html; charset = gb2312"/>
<Title> radio value of the php read single-choice button </title>
</Head>
<Body>
<Form id = "form1" name = "form1" method = "post" action = "">
<P>
<Label>
<Input type = "radio" name = "RadioGroup1" value = "1"/>
Single choice </label>
1 <br/>
<Label>
<Input type = "radio" name = "RadioGroup1" value = "2"/>
Single choice </label>
2 </p>
<P>
<Label>
<Input type = "submit" name = "Submit" value = "submit"/>
</Label>
<Br/>
</P>
</Form>
</Body>
</Html>
<?
If ($ _ POST)
{
Echo 'select a single select', $ _ POST ['radiogroup1'];
// Since the attributes of a Single-choice button can only be selected at the same time, it is OK to directly change their names to the same one.
}
?>
The main idea is how to maintain the value of a single-choice button in php.
Copy codeThe Code is as follows:
<Input name = "sex" type = "radio" value = "male" <? Php if ($ _ POST ['sex']! = "") Echo "checked = checked;"?> /> Male
<Input type = "radio" name = "sex" value = "female" <? Php if ($ _ POST ['sex'] = "female") echo "checked = checked";?> /> Female
We also recommend that you do not use Chinese characters for identification. 0, 1 represents male and female.
