在PHP中使用Echo Submit Button

Question

I am trying to echo a submit form in my php code:

I am trying the following:

// Display results
foreach ($media->data as $data) {
echo "<a href=\"{$data->link}\"</a>";
echo "<h4>Photo by: {$data->user->username}</h6>";
echo $pictureImage = "<img src=\"{$data->images->thumbnail->url}\">";
echo "<h5>Like Count for Photo: {$data->likes->count}</h5>";
echo "<form>";
echo "<form action='tag.php' method='post'>";
echo "<input type='submit' name='submit'>";
echo "</form>";

}

Then:

if(isset($_POST['submit'])) {
echo "hello";
}

This doesn't seem to echo "hello";

Any help would be appreciated

Answer 1

You're missing a closing parenthesis:

if(isset($_POST['submit'])) {
                          ^
                          Here

Answer 2

You're missing a value on the input tag. Change it to:

echo "<input type='submit' name='submit' value='Submit'>";

Answer 3

  echo '<input type="submit" class="btn btn-primary" value="Active">';

Answer 4

It should be

if(isset($_POST['submit'])) {
                          ^
 echo "hello";
}

you missed a parenthesis.

Edit: Also it should be:

<input type='submit' name='submit' value='submit'>

Else $_POST['submit'] will not get set.
