Question

我正在尝试提交一个HTML表单，其中包含3个不同名称的提交按钮，但我无法识别哪个按钮提交了表单。

HTML：

<div class="col-md-12">
    <form id="validation-form" class="form-horizontal form-label-left"
    data-parsley-priority-enabled="false"
    novalidate="novalidate"
    action="./controller/productlineNewController.php" method="post">
        <div class="col-md-6">
            <section class="widget">
                <div class="body">
                    <fieldset>
                        <div class="form-group">
                            <label class="control-label col-md-4" for="pl_name">Product Line Name *</label>
                            <div class="col-md-6">
                                <input type="text" id="pl_name" name="pl_name" onBlur="checkAvailability()"
                                class="form-control input-transparent"
                                placeholder="Enter Product Line Name" required="required">
                                <span class="help-block" id="availability-status"></span>
                            </div>
                            <p><img src="img/small_loading.gif" id="loaderIcon" style="display:none" /></p>
                        </div>
                    </fieldset>
                </div>
            </section>
        </div>
        <div class="col-md-12">
            <section class="widget">
                <div class="form-actions">
                    <div class="row">
                        <div class="col-md-10 col-md-offset-2">
                            <button type="submit" name="save" class="btn btn-lg btn-success"
                            onclick="needToConfirm = false;">Save</button>&nbsp;
                            <button type="submit" name="save_new" class="btn btn-lg btn-success"
                            onclick="needToConfirm = false;">Save &amp; New Product Line</button>&nbsp;
                            <button type="submit" name="save_project" class="btn btn-lg btn-primary"
                            onclick="needToConfirm = false;">Save &amp; Add Project</button>&nbsp;
                            <button type="button" onclick="resetForm()"
                            class="btn btn-lg btn-danger">Reset Form</button>&nbsp;
                        </div>
                    </div>
                </div>
            </section>
        </div>
    </form>
</div>

PHP - productlineNewController.php

print_r($_POST);
if (array_key_exists("save", $_POST)) {
    $action = TRUE;
    $new    = FALSE;
    $task   = FALSE;
    echo 'save';
    } elseif (array_key_exists('save_new', $_POST)) {
    $action = TRUE;
    $new    = TRUE;
    $task   = FALSE;
    echo 'save_new';
    } elseif (array_key_exists('save_project', $_POST)) {
    $action = TRUE;
    $new    = FALSE;
    $task   = TRUE;
    echo 'save_project';
}

结果：

Array ( [pl_name] => aaa )

我已经尝试isset函数来检查是否点击了任何提交按钮，但我什么都没有。

我还尝试使用input

的buttons内容

<input type="submit" name="save2" id="save" class="btn btn-lg btn-success" onclick="needToConfirm = false;" value="Save">&nbsp;

但同样的问题。

请帮忙。

edit

当我从JS页面中删除此HTML代码时，它工作正常但我需要此JS代码来验证表单。任何人都可以解决这个问题。

        <script src="lib/parsleyjs/dist/parsley.min.js"></script>

Core PHP中使用的此方法以您的方式尝试

<?php
    if (isset($_POST['save'])) {
        # save was clicked
    }
    else if (isset($_POST['save_new'])) {
        # save_new was clicked
    }
    else if (isset($_POST['save_project'])) {
        # save_project was clicked
    }
?>
