Question

当输入的href为空时，我会制作此系统，图标将被隐藏，但对我来说这不起作用，

我尝试了一些方法，但没有用。谁知道什么是错的？

我有这段代码：

public boolean hasProduct(ArrayList customerList, String p)
{
    return customerList.contains(p);
}

Answer 1

您的运营商不正确：[WebMethod] public static string GetCustomers(int pageIndex) { return GetCustomersData(pageIndex).GetXml(); } public static DataSet GetCustomersData(int pageIndex) { string query = "[sp_pro_MuroPosts_PageWise]"; SqlCommand cmd = new SqlCommand(query); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.AddWithValue("@PageIndex", pageIndex); cmd.Parameters.AddWithValue("@PageSize", 10); cmd.Parameters.Add("@PageCount", SqlDbType.Int, 4).Direction = ParameterDirection.Output; return GetData(cmd); } private static DataSet GetData(SqlCommand cmd) { cmd.Connection = clsBaseDatos.sqlConexion; using (cmd.Connection) { using (DataSet ds = new DataSet()) { SqlConnection cnn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConexionBD"].ConnectionString); SqlDataAdapter sda = new SqlDataAdapter(); cmd.Connection = cnn; sda.SelectCommand = cmd; sda.Fill(ds, "vw_Muro_Posts"); SqlDataAdapter cmd2 = new SqlDataAdapter("SELECT * FROM vw_Muro_Comments WHERE COMM_ESTATUS != '0' ORDER BY cast([COMM_FECHA] as datetime) DESC", cnn); cmd2.Fill(ds, "vw_Muro_Comments"); //Aqui se hace el join de los dos repeaters ds.Relations.Add("myrelation", ds.Tables["vw_Muro_Posts"].Columns["POST_ID"], ds.Tables["vw_Muro_Comments"].Columns["POST_ID"], false); DataTable dt = new DataTable("PageCount"); dt.Columns.Add("PageCount"); dt.Rows.Add(); dt.Rows[0][0] = cmd.Parameters["@PageCount"].Value; ds.Tables.Add(dt); return ds; } } }

试试这个：if (!get_theme_mod(('pocketcars_url2') == '' ))

if ( get_theme_mod(('pocketcars_url1') != '' ))

Answer 2

<?php $text = esc_url(get_theme_mod( 'website_url1' )); if($text != '' ) : ?>
  <a href="<?php echo esc_url( get_theme_mod( 'website_url2' ) );?>" class="social1">
  <i class="fa fa-twitter" aria-hidden="true"></i></a>"
<?php endif; ?>
