我尝试使用数组......
<input type="checkbox" name="mes[]" value="01">January
<input type="checkbox" name="mes[]" value="02">Feb
<input type="checkbox" name="mes[]" value="03">March
<input type="checkbox" name="mes[]" value="04">April
<input type="checkbox" name="mes[]" value="05">May
<input type="checkbox" name="mes[]" value="06">June
<input type="checkbox" name="mes[]" value="07">July
<input type="checkbox" name="mes[]" value="08">August
<input type="checkbox" name="mes[]" value="09">September
<input type="checkbox" name="mes[]" value="10">Oct
<input type="checkbox" name="mes[]" value="11">Nov
<input type="checkbox" name="mes[]" value="12">Dec
<input type="submit" name="reporte_mes">
</form>
php-mysql代码的一部分:
if(isset($_POST['reporte_mes'])){
$busqueda_cad = implode(',', $_POST["mes"]);
$sql = "SELECT bien_catal.bien, categorias.nombre_categoria,
marca_catal.marca, color_catal.color, modelo_catal.modelo,
area_catal.area, condicion.condicion, products.caracteristicas,
products.stock, products.precio_producto, products.date_added,
products.codigo_producto, products.observaciones FROM products
LEFT JOIN bien_catal ON (products.fk_bien = bien_catal.id_bien)
LEFT JOIN categorias ON (products.fk_categoria = categorias.id_categoria)
LEFT JOIN marca_catal ON (products.fk_marca = marca_catal.id_marca)
LEFT JOIN color_catal ON (products.fk_color = color_catal.id_color)
LEFT JOIN modelo_catal ON (products.fk_modelo = modelo_catal.id_modelo)
LEFT JOIN area_catal ON (products.fk_area = area_catal.id_area)
LEFT JOIN condicion ON (products.fk_condicion = condicion.id_condicion)
WHERE FIND_IN_SET(products.date_added, '$busqueda_cad')";
查询很好,它显示没有WHERE的所有行,但是从WHERE开始,它没有显示任何内容。
答案 0 :(得分:0)
你的变量$busqueda_cad
是几个月的数组吗?因此,WHERE
正在查看专栏products.date_added
,并尝试将其与一个月匹配?
我认为应该是这样的[COLUMN OF MONTHS]这个列可以保持你的月份当然
WHERE FIND_IN_SET( [COLUMN OF MONTHS] , '$busqueda_cad')";
